I don't tan at all. Every bit of my background is populated with Nordics who turn into Crispy Critters in the sun. I already had several second degree sunburns as a kid, and so now I cultivate my lily white computer screen tan.
I freckle a bit when exposed to a small amount of sunlight, but for heaven's sake, I got a sunburn in Ireland. IRELAND! 3 non-consecutive days of sunshine in two weeks, and I burned the skin off my nose (even though I was wearing sunscreen).
