Part of my reason for choosing UV Awareness is that last year when I was building my garden I got a severe sunburn. On a Saturday. I had to fill in for the Church pianist the next day. Not fun. I wore a sleeveless dress, and every time my hair touched my shoulder, I thought I would scream. A year and a couple months later, there is still a faint line on my shoulder. So, learn from my mistake: if you've already applied sunscreen and your skin feels like it's burning, it is! Don't ignore it, go put on more sunscreen.
