Input: Text: this fu was a year ago, and it taught me to never nod my head in response to a question or something i didn't quite catch or understand. 

a bit about myself, i'm a teenage guy from singapore, and despite the fact that i look chinese, i am not. along with the fact that i still take mandarin chinese as a subject in school, most people tend to think that i'm chinese, but it doesn't really bother me. apart from the fact that i really, really suck at understanding it. 

anyway, so i was having a haircut in a neighborhood hair salon. i don't usually go to these sort of places to get my hair cut, i go to the ones in shopping malls and all which cost 10 bucks for one session. the hairdressers/barbers in those place usually speak english. this one is a young chinese man, probably in his 20s, and he was speaking to me in mandarin mostly and fragments of english, which i could roughly understand. or so i thought. 

this is where the fu comes in. he asks me a question in chinese before he begins cutting my hair and all, which i dismissed as some random question like "are you ready to have a haircut?" or something along that line. i nodded my head in response, which would end up being one of the most pivotal and tragic decisions of my life. 

after a few minutes, i notice that the hairdresser was already in the process of cutting my hair bald. turns out, he had asked me in mandarin whether i wanted to go bald. it was too late to protest at this point, so i had no choice but to suck it up and prepare for a whole lot of teasing in school the next day.

and that's when i learnt to never mindlessly nod my head, ever again.
