Well......do they? The saying goes 'sweating like a pig'. I'm no pig but I sure did more than my fair share of sweating today. It was at least 90º F and steamy as all get out. It was so warm at Panera's tonight for knit group that I had to leave. I don't care much for this type of heat. If it got up to 70-75º all Summer long I'd be happy. Happy as a clam --- say, are clams really happy??
