do remember when your parents are taking you to some kind of places but you are bored and they don't let you watch you're phone or tablet.

mom how long it will take

not much just wait

try by looking at the clouds to see a human, 

 a castle, a cat or something else then in your mind try to do a little movie that it would be more fun.

if that didn't work then try this one

try counting or doing some kind of tricks with your fingers.
