Hey, we're the same age.

For me, time is moving uncomfortably fast at this point. It makes me nervous sometimes. A year goes by in a short time, seemingly. I remember being 6 years old and the month of December felt like eternity becayse of waiting for Christmas. When school got out for the summer, the 3 months off felt ;like an eternity, I remember thinking to myself "well, I basically never have to go school again!". Now, 3 months passes before I realize.
It seems logical that as you get older, time seems to pass faster, because you spend less and less time truly processing your input, so you notice less and less, and get absorbed into your routine.
