I recently visited an outlet store and asked friend if she wanted anything. She said x, y, z. Totalling £20.
That was 2 weeks ago. She's not mentioned collecting them. She never sent the money and in the meantime my birthday passed and she didn't even call or send a card (we usually got out for lunch and do presents but I didn't hear from her at all bar a generic happy day txt)
I got some of the items myself and really love them and wish I'd gotten more. It's far away, the outlet!
AIBU to just keep the ones I bought for her and if she asks for them in the future just say 'well you never mentioned them or paid for them so I assumed you didn't want them after all?'
