depends. after that length of time i might not still be playing the character, or i might be playing them differently enough that the thread would have gone differently, or i've gotten over the kink or concept that drove me to be interested in the thread in the first place.

i'll definitely have a moment of "how did you even still have this" but i'll most likely conclude that some kind of rl bullshit hit you hard for awhile and you're just now getting back to rp, and that's not weird. assuming no other red flags, just getting a late tag back isn't enough to weird me out.

if none of the above things has happened to make me not care about the thread anymore, i'll still tag it back. but there's a really high chance of one of those things happening. if i was really into the thread before, i might drop you a pm like "hey i'd love to rp something because i really liked that thread but i've kinda lost the feel for that one, anything else you want to do?"
