The only gift I get peeved about is like, aquarium item trash with no resale value and a 1g marketplace value. That's not a gift. That's saying "Here, throw this out for me". It happened a lot during last year's Christmas event because it had a gifting requirement...I mean, clearly those people didn't think you wanted it. I'm glad they didn't have that req this year, it really drowned out the thoughtful anons. Other than the aforementioned items, I don't care about price. I like the people who have stories or personalized messages!
I do try to say thanks in posts...never sure people see them. I post in the anon threads, but I usually have a hard time keeping up with a convo while gifting.
I give gifts at other times...not so often though, I kinda forget. I always think about my gifts but I still get it wrong sometimes. It happens.
I got coal once too...I think it was just that anon's theme. Other people posted that they'd gotten it around the same time. I dunno, unless the message said "I hate you", it could have been the theme guy.
