Nope! I might get a little disappointed. I do get more disappointed, however, if I try to tag them more than once and never get a tag back, or get a tag and then a promptly dropped thread.

I do get a little buttpained when I see a person around a LOT in memes and they seem to never respond to any tags, or consistently only tag one person who responds to them, or have one or two threads they drop and don't bother to tag any of the other people. But that's mostly a mix of selfish disappointment and "wtf why are you wasting people's times if you don't ever actually do meme threads?"
