What the Lick?

So yesterday, I was going to swim team. I'm not going to swimming today because it's just a swim meet, and those aren't fun. Anyway. I was thinking to myself "I should put on some sunscreen" because last week I was a really big slacker dealing with the putting on-ness of sunscreen! So I put some on, and I think I got sunburned yesterday!?! What the lick? How in the WORLD does that work? Then later, I felt really dumb. I went night-swimming with my friends last night and I was thinking "Do I need to put sunscreen on?" Then I remembered the sun was gone. Ha.
