I got suspended from school because of a misunderstanding what should I tell people when I get back?

Well... A good excuse you could tell them... uhmm... "My family kinda decided that i will transfer to some school so I tried them out..." or "I got lost in a forest after a climbing" or "i was hospitalized and its fine now" (too brush it off easily)... that's all I can think for the while... since I don't know much of what really happened... well.. for your friends... tell them not to tell others and tell them why you don't... but if the moment you got back and they all asked "Why you got suspended (let's assume they know" just tell them your side first... and then tell them this way "(your side)... and then they suddenly tell that I etc etc etc..." wished I helped.

Just say you had a "family emergency." If they're not close friends, they won't ask what it is about. If they do ask, brush it off as unimportant and saying something like, "Oh, don't worry, it's all good now. I really don't want to talk about it."Really, people can be nosy, so I understand how you're feeling.
