When I was a kid, my mom didn't want me to get burnt by hot water so she told me "always turn on cold water first, never hot water first!"
So I asked her: "Will it explode if I turn on hot water first?"
And she answered - probably absentmindedly- "yes!"
I never ever ever ever ever turned on the hot water tap first! XD Even now - I'm 22 - I would feel strange doing so!
But I never got burnt anyway so thank you mom!
