I have a boy in my class who comes in every morning with messy hair
我们班上有个男同学，每天早上来上学的时候，头发都是乱糟糟的

and every day I comb his hair for him.
每天早上我都为他梳头发

his morning when I got done he gave me the biggest hug and said,
今天早上，我给他梳完头发时，他给了我一个大大的拥抱

"Thanks Mr. Boyd, my mom is sick and can't brush my hair anymore, so I'm happy you do it."
“谢谢你，Boyd先生，我妈妈病了，不能为我梳头发了，我很开心你能帮我梳”

I literally started tearing up.
那一刻我真的眼中充满了泪水

ALWAYS be kind,
请此刻保持友善

you never know what kind of struggles someone is facing.
你永远不知道，对方正处于怎样的困境

This is the happiest, sweetest baby.
那是我们班上最快乐，最惹人疼爱的孩子

I would've had no idea about this struggle had he not told me
要不是他这样说，我根本看不出他家里的处境
