It was always both fun and annoying when dad would give me a big hug after skiing when we had our ski stuff put away. He’d always manage to get frosty icicles broken off out of his beard on my neck and down my shirt just after I got warm and dry. Another technique he perfected is the second car-door crossdraft when changing out of damp, partially frozen ski clothes on a cold, windy day. The very moment one door was open, he’d open another, immediately cooling any ambient warmth in the vehicle down to about 0.2º warmer than the outdoors. Now the complaints of my fellow passengers resonate when I inadvertently pull the same stunt!
