Sometimes it's hard to be lonely, imagine being an only son and and you live in an estate where other kids aren't allowed to come out and play in the evening . You definitely would learn how to survive on your own trust me . That's when funny ideas like this come into your head.
Speaking from experience ...I remember having to ride the see-saw once on my own by putting a heavy Stone on the other side . Lolzzz.....it was fun though, atleast I got to enjoy myself like this man on your gif...hahaha
