Pool days

Today, it was warm enough in the afternoon to take a dip in the pool. The pool was chilly, but I went in anyways. But, it makes me wonder if this was the last day to swim this year. The temps are supposed to go down over the next few days, and it gets really cold at night now. So, the pool doesn't hold the heat anymore.
It makes me sad, because the days are getting shorter, school starts next week, and while the official end of summer isn't for a few weeks, I still feel like summer is almost over.
