you shouldnt tell people to shut up. it's usually perahps and probably maybe most likely a personal jab that refers only to personal issues and thus lightly must i brush strokes on the canvas of lively, no. to express yourself justly thus, unless you are hating on people you know nothing about, is a must.
oh hey btw, having english as a second language doesn’t measure someone’s intellect and the like, it’s ok to have bad grammar and bad english, it’s a means of communicate, not a measure of smarts, but you must know the difference, since you’re not cheap shot for other reasons.
