i lied about my age to play roblox games

so i kinda fibbed abt my age 2 sign up 4 roblox cus the min age is 9 and im only in like grade 5. i was all proud of myself coz i tricked it lol but now its kinda bothering me cuz i dunno if they r gonna find out. also idk why i feel bad when no one got hurt or anything... maybe its jus a big deal 4 me cus ive never done somethin like that before
