How to cope being 25 and being called old?

21 year old look at you as if you're a uncle or some shit but you still feel 21 but you know you're not.

I'm not in that 20 to 24 'young' age bracket anymore. I don't even feel like a adult either but I don't feel like a teenager either. It's a weird age to be in.

I find myself reminiscing and wishing I can be 22 again. Time keeps going faster each year.
