My landlord always gives me a birthday gift. He is too kind I know, but he never delivers the gift by himself, instead he leaves it in the common kitchen.
Sometimes he also gives us a piece of cake by putting it somewhere in our common room. Sometimes he leaves something that I don't really know if it's meant to be for me or he just forgot to pick it up. I don't know if there is a need to communicate with him about this issue, because I find it really difficult to ask a person if they mean to give me a gift - nobody does!
I don't really understand this behavior because I deliver my gifts in person, and I receive gifts also in person (unless we live too far).
If I pick something he left and that wasn't meant for me, then it's really awkward, if I don't pick it up then, maybe he'll think I reject his gift.
Is it common to leave something in someone's house and expect them to think it's a gift for them?
