So when we arrived there we actually found a volleyball.
Are you sure there was a volleyball?
Yes and I took it too.
It is strange you found a volleyball there, but it's not something you should just ignore. If it was there randomly then someone lost it and you should report it instead of stealing it.
Ugh I just wanted to take it home though
Well if it's not yours then you shouldn't, that's considered stealing. You should just try to find whoever it belonged to.
