An insane delusion is a belief which has absolutely no foundation in fact, and even slight evidence which provides a basis for the belief negates the existence of a delusion. Yett v. Yett, 44 Or. App. 709, 714, 606 P.2d 1174 (1980). We conclude that, although the decedent's perception or remembrance of events may have differed from those of his children, there were events which provided at least a slight basis for his statements.

That definition has been applied in numerous cases since Potter. See In Re Walther's Estate, 177 Or. 382, 163 P.2d 285 (1945); Parrott v. Creson, 132 Or. 234, 285 P. 224 (1930); In Re Sturtevant's Estate, 92 Or. 269, 178 P. 192, 180 P. 595 (1919); Yett v. Yett, 44 Or. App. 709, 606 P.2d 1174 (1980). Our review of the record satisfies us that there is evidence to support decedent's belief that neither of his children liked him, although it may be an overstatement to say that they hated him.
