 If i was invisible, i could do many things. I could sneak in an take sweets from the top without anybody knowing. I could play and scare numerous friends. When playing hide and seek, no one could find me.

 It could be really fun. I could play pranks on people. I could scare friends by may means, It would be quite fun.
