Where a gift is in the form of a single transfer to the same person of several things of which one is, and the others are not, burdened by an obligation, the done can take nothing by the gift unless he accepts it fully.
     Where a gift is in the form of two or more separate and independent transfers to the same person of several things, the done is at liberty to accept one of them and refuse the others, although the former may be beneficial and the latter onerous.
     Onerous gift to disqualified person.-- A done not competent to contract and accepting property burdened by any obligation is not bound by his acceptance. But if, after becoming competent to contract and being aware of the obligation, he retains the property given, he becomes so bound.
