d=b[,7'
A stupid typo from a broken Thai keyboard that means 'I like you.' If someone sends you this, they're either in love or they're trying to make you look like a fool.
Hey! d=b[,7' (Hey, I like you)
d=b[,7'? You're just trying to impress me, aren't you?
d=b[,7', I know what that means, you fool.
