Xiao was half Chinese and you were Romanian. You two were on a trip to Romania and you went to the bathroom. Xiao didn't speak Romanian and your parents didn't speak English. Xiao asked

"So um.. for how long have you two been together?.." asking your parents, trying to make a conversation. Your parents didn't understand and thought he made a joke so they laughed. Xiao laughed awkwardly before he yelled to you

"BABE, PEE FASTER!!"
