I've turned into a wimp!
I grew up in Iowa where it can get pretty cold in the winter. I spent 7 years in Wisconsin and endured 30 below temperatures at times. And 10" of snow at the end of April. And yet, in Greenville, SC, I freeze when it gets below 60! People laugh at me for being bundled up in a sweater and a light coat. I really want to wear my warmer winter one, but when it gets "really" cold I won't have any more warm layers to put on!
Please understand, living on a tropical island thins your blood. If you get too cold inside the air conditioning (or air con as it's called there), you go outside to warm up!
I will be in Iowa for 3 weeks over Christmas. I think I'll turn into a human Popsicle. They've already had snow there. It will be good to be with family, but I think I'll be wishing we could all be together on the beach - where I spent Christmas the last two years! They don't know what they're missing! :-)
If the weather gets cold in your area and you need a new coat, I found some on clearance (50% off or more) at Amazon for women and men. Christmas idea for the sports fan in your family - the men's clearance had quite a few different styles of lightweight NFL jackets 60% off!
