Ohhhh I see, you’re one of the people who think Tumblr is a special teenagers’ club, as opposed to a blogging platform frequented by people of all ages.
Most of the people I’m friendliest with here are in their twenties or thirties. Some in their forties and beyond. Fandom isn’t just for teens, though it is absolutely for them too. I do have some friends that are teenagers. One of the things that’s great about coming here is despite things like age and the fact we live in different countries, we still enjoy things together.
