the services, to pay the reasonable value thereof, and there is presumed an implied contract for the payment by the latter of the reasonable value thereof; (b) but a presumption may arise from the relationship of the parties that services, if any, were rendered as acts of gratuitous kindness, and such relationships giving rise to presumption that the services rendered were gratuitous may arise from a family relationship, or (c) from some other close relationship, such close relationship being one that in the experience and customs of men would lead the ordinary person to believe that any services rendered were rendered gratuitously, and it is a question for the jury to determine whether such close relationship existed between Nelle Taylor and Nan Durst, and it is a question for the jury, taking into consideration all the circumstances including the nature and degree of the relationship between Nelle Taylor and Nan Durst and their circumstances in life, to determine whether there was any ■implied contract for compensation and whether there was any intent on the part of Nelle Taylor to charge and on the part of Nan Durst to pay for services rendered if any.
“(d) Now, if the jury finds from the evidence in this cause that Nelle Taylor rendered services to Nan Durst in taking care of her and working for her, and that Nelle Taylor intended while rendering such services, if any, to charge Nan Durst for the same and that Nan Durst intended to pay for such services, if any, then you will find the issues for Nelle Taylor, the plaintiff, and allow her in your verdict such sum as you may believe from the evidence in this cause that she is entitled to as fair and reasonable compensation for such services as you may find that she rendered.
“(e) The jury is instructed on the other hand that if the jury believes and finds from the evidence in the cause that plaintiff rendered the services, if any, sued for as acts of gratuitous kindness to Nan Durst and because of her close personal relationship with Nan Durst with no intention at the time of charging her for the same, then you must find the issues for the defendant and in such case it makes no difference how meritorious and valuable her services, if any, to Nan Durst may have been.”
It is apparent the instruction incorporates two or more theoretical circumstances which may give rise to a “presumption”, one of which is “a family relationship”. There is no evidence in this case, and no contention made, that such a “relationship” existed. Such a theoretical situation had no place in the instruction and would only tend to confuse rather than enlighten the jury.
The instruction also informed the jury that a presumption may arise “from some other close relationship, such close relationship being one that in the experience and customs of men would lead the ordinary person to believe that any services rendered were rendered gratuitously, >>'* This quoted language is so broad and general that it gave the jury a roving commission to decide, each for himself, what would constitute “close relationship”. The only guide given the jury in determining what would constitute such a close relationship is “the experience and customs of men”. That is about as indefinite, uncertain and ethereal as could be expressed by so few words. Instructions should not incorporate a discourse on general principles of law.
The drafter of the instruction fell into error by incorporating in the instruction general language used by appellate courts in certain cases. See Shern v. Sims, Mo.App., 258 S.W. 1029, 1031, and Hyde v. Honiter, 175 Mo.App. 583, 158 S.W. 83, 87, 88. The fact that language used in an instruction may be found in the reasoning or conclusions of an appellate court, or of a law text book, does not make it proper language for an instruction, regardless of how authoritative and wise it may be; and this is especially true when it is used in an abstract manner.
