RE: How to dress for 65 degrees?
If it's 65 sunny and no wind, short sleeves and long pants. If it's windy, long sleeves.
Jackets or sweatshirts when it's below 50 or so, depends on the wind. Coats when the windchill goes below freezing. DS always wears a hat, usually a ball cap (he's sensitive to the sunlight), but I change it to a winter hat if it's below freezing. DS usually refuses mittens, so I only insist on them when we play in the snow.
DS, age 10: first decade of parenting done, nine more to go!
