I joined a climbing gym after learning how to climb, belay and rappel for a week. I love learning knots, so that’s fun, but also all the terminology and techniques. Plus there’s a whole social aspect to it (climbers tend to be pretty friendly). Turning out to be a healthy and exciting new hobby!
Also @fool I remember learning to whistle as a kid–my dad was slightly annoyed he had shown me how to do it because I wouldn’t stop whistling the main themes from Indiana Jones and Star Wars
Knew this was it immediately, beat me to it! 😄
