why wy?

Went climbing last night, and I was amazed at the number of young people there. I did a very juggy 12 (like a 5a i think), which was a nice warm up, and then this six year old girl started leading it...to be fair (to me, that is), you have to pass a leading and belaying test in order to lead, and I haven't sorted that out yet.
There was also a short kid (maybe around 12) with the biceps of a man... and the very muscular middle-aged woman who was all power (she was doing an constant overhang, like the rightmost yishun one). I did about 8 5b-5c climbs, and a couple of short ones, and then i got home and my mom wanted a massage... ouch
