1. When you go back on Tumblr after a while and there are all new memes you’ve never seen.
2. When you agree with every post that involves saying “me,” “same,” or something about how you’re “trash” because you know it’s kind of true.
3. When you try to explain to non-Tumblr users (namely, your parents) about Tumblr or why that meme is hilarious but they just don't get it.
4. When those same people just stare at you like you’re crazy but you swear it’s funny.
5. When that blog you love doesn’t follow you back.
6. When that blog you love does follow you back.
7. When you look at the clock and realize that you’ve been on Tumblr for 6 hours and it’s 3 AM and you realize that Tumblr is a vortex you can never escape but you love it anyway.
