Ofc something nice and thoughtful is ideal But this guy didn't give us anything to build off of, other than roblox and not robux

If you know someone and they like gifts: give something useful they would like, but haven't bought themselves (if they like things to have a use) or something that doesn't need to have monetary value, like something more personal and thoughtful (if they like decorations and things with personal value)

If you don't really know the person or they don't really want random stuff: money, because even though it's not the best gift out there still it's better than something they wouldn't use or already had
