Are scars triggering to the majority?

(I’ve been clean for 66 days so im not planning to have any fresh/open wounds)

I was wondering whether or not the it’s appropriate. since near my ankle i have 1 huge noticeable scar my long shorts won’t cover. For context I’m going to be in a wet environment with friends and classmates.(water day) I don’t want to make anyone uncomfortable. However i don’t mind questions since i have a pot full of lies i can tell. Also it’s a school event so i was wondering if any teachers could legally ask me about it or something. (i live in florida) I really want to go since all my friends are going to be there but if it’s not possible than that’s fine.
