Well usually going to bed or studying for tests. Perhaps busy or just waking up. TPT used to be way active from 2010-2015. At its height 2010-2012. I just seem to care about the future of TPT community, that's what keeps me coming back here. Life gets complicated especially from middle school and up from there. That could explain so much absence.
Honestly, I left TPT for like two months there, and when I came back I was surprised how active it is.
Meanwhile, another forum I'm in, which used to have multiple posts a day per subforum, averages maybe 1 post per day, apart from one part which is still active (but it's the forum for a youtuber, so it's just the part talking about his videos)
