I think it'd be nice if you could accept it- not always but once in a while.
I know I couldn't but that's me and I've been told by my T that not being able to accept a gift just because the person wanted to do stg nice for me (like I'm OK when there's a valid reason behind it like I have a b-day and it's from someone I give presents too) without
A. thinking there has to be some secret reason behind it that I'm not aware of and stressing over it.
B. needing to reciprocate immediately
C. refusing the gift
Is not OK and shows that I don't trust ppl, like to keep the upper hand in every relationship possible and am doubting my self worth.
So yeah I think my T would be thrilled if I were to accept that. Though I can see how not being able to buy him a cookie/coffee could be a problem...
