Why would you think of AK's crying as something to "tolerate"? Why does it upset you in any way? Do you have trouble tolerating joy, anger, or fear, or just sadness/frustration?
JazzSpazz treated the crying as humorous, and as any Puppeteer will tell you, humor is based on an interrupted fear reflex.
I agree that making fun of crying is rooted in cultural aversion to the expression. But, surely humor is not ONLY based on interrupted fear reflex! Not even mockery humor is solely based on that.
