Friends invited us to stop by their beach house today when they heard we were going to be in the area, and said they were going to take their boat out to watch the sunset. We had a great time with them and meeting their other friends who were visiting from the city. When we were getting ready to go out on the boat, I told the friends to bring hoodies, sweaters, blankets, whatever. The city slickers were like, "What?! No way, it's 90 degrees out!" I told them it gets really cold on the water, and they'd regret not having something to keep warm. They blew me off. Pretty much as soon as we set out, you could see everyone getting goosebumps, and then fully shivering when we picked up speed. Fortunately our hosts had plenty of blankets onboard, but I was just shaking my head.
