Well, maybe you could run around the playground acting like Mario in the game? And if you play it for awhile, someone may notice you and ask to play with you.
Hey, thanks for the useful tips. Yes, I do play a imaginary game in my mind called "Super Mario 64 DS 2". You battle new bosses and have new techniques!
What? That's terrible. :< I was lonely a couple of times in Elementary School, especially in third grade. I don't know what to say. What I did was I tried to make it fun to be by myself. I invented games up for Recess to play by myself, played them, and highly enjoyed them. Try that. Don't stop having fun because it's not with someone else. Put imaginary players into it, and play with those. Then, after awhile, if you're patient, maybe a friend will come along. :3
Have you been lonely at school before? I am in Elementary School. Yes, I am very lonely in class and recess. I have my desk pushed out away from the others and at recess I sit by the school's wall, bundle up, and sleep. Yes, berry lonely...
