I believe in him.Peter Pan is a famous character who may be real (only if আপনি believe).Peyer Pan has been my childhood movie and it still is.If আপনি really believe in Peter all আপনি have to do is say I do believe in পরী I do I do 10 times,sing slow songs about him and tell stories about him and/or his adventures.I've done it before.So I truly believe in him and টিংকারবেল too.
But if আপনি don't believe in him অথবা Tinkerbell..well whenever someone doesn't believe in a fairy then they die (and that's what could happen to টিংকারবেল if আপনি don't believe) and Peter Pan might disappear অথবা might not go to your house again.So believe in them and they might take আপনি on an adventure.
