I have regifted and been regifted. Bad examples:
I was married when younger (a few years ago...I'm still young), anyway...my like 3rd cousins, my Great Aunt's kids, who are older than my parents sent me some little blue (barely) hand towels with pink satin big bows on them....the bad part? They were dirty! I couldn't be mad because these two are so old and cute. So, I just wrote a thank you and figured they were saving for later
I got regifted this Christmas. I had a Christmas party with my sisters from my chapter in Kansas City. There was this sister and I who hated each other in college, well...she shows at the door with a crappy candle thing, I'm not into crafts at all, but you could tell she just picked it off the shelf, because it was all dusty inside. She hugged me and said, "let's let bygone's be bygone's", which is cool. So, I shoved the thing in my mom's stocking before Christmas morning and she loves the scent so she didn't care one bit
