That post-pool trip feeling.
I love that feeling of being just barely sunburnt. Not "burnt to a crisp" where you get blisters and peeling skin, but that feeling where you're warm and sleepy. It reminds me of the countless times my parents would take me and my brothers to our neighborhood pool when they had an hour or two to spare.
We'd splash around for an afternoon, and since we were all paler than bleached paper we had to constantly reapply sunscreen. But, despite my parents' hard work at coralling three toddlers, we would still get burnt anyway. We'd head home after a while, our eyes stinging from the chlorine and our hair stiff from the water. We would then wait for our dad to make us some post-pool sandwiches. They were the same as any other sandwich we would get for our lunch, but something about eating them after swimming for hours made them taste... better? After that, it was time for a nap. That's where one of my favorite feelings in the world comes from: lying in bed, slightly radiating heat because I got a little sunburnt, slathered in aloe, and peacefully drifting off to sleep. I have lived through that feeling hundreds of times, and every time I feel it I am always brought back to being a happy little kid, oblivious to everything and loving it.
