No one shouldn't be afraid of saying you are a nerd.
People can't say you aren't a nerd.
They aren't in your mind and know what you like and dislike.
Nerds aren't just ones that play pokemon which is pretty cool if you like it.
Don't say," oh you aren't a nerd."
I know you are older, but nerds had change or you just don't what nerds are like.
You are just thinking about the stereotype.
