I have a friend within a group who sees give giving as a transactional thing. If someone buys her a gift she sees the need to reciprocate and likewise if she buys gifts then she is miffed if she doesn't get one back.
I alway buy her a Christmas gift and don't expect one back. There are reasons but outing so I won't go into it. Suffice to say I'm happy to buy her a gift and wouldn't expect her to buy one for me. She does which is fine but most years she will ask me around this time "Are we doing Christmas presents?" or want to agree an exchange date. I feel like telling her that I'll buy her a gift but don't need one in return or better that she can wait and see if she's getting a gift!
Easter eggs is worst as I used to give an Easter egg (again there was a reason at the time) and she would get me one back but now she'll ask me if we are exchanging Easter eggs and to be honest I don't really want to sometimes as I have enough on with my children and nieces and nephews. I want to say that I'll hit an Easter egg if I feel like but not have another one to add to my list.
I'm also conscious with how she views gifts of spending a certain amount so that she's not spending more than me but I may be overthinking.
We are both generous people so this isn't about anyone being tight just clearly having different appreciates to giving presents.
