Mom has this belief, since she can't remember that all the clothes/shoes, etc. that she has in her closet belong to her. She claims someone comes in house and leaves their clothes behind. If I say that ok, if they aren't your's let's get rid of them, no we can't. (no reason given). What to say to get around this?
:-D
I had the pleasure of telling mom that any time I got her dressed in street clothes. "Oh, mom! So glad you like it -- just came yesterday!" ;) ;)
"hmm ... they seem to be all your size. Do you suppose someone is returning things they borrowed a while ago? Or maybe leaving you a gift?"
"however this got here it really is a nice outfit, and just your color. Why don't you just wear it? You even have some jewelry that would like with it."
"If you don't want to wear them and you don't think they are yours, let's fold them up and put them in a box, in case someone realizes their mistake and asks for them."
Is your mother disturbed or anxious that these "strange" clothes are showing up? If not, just take it in stride.
