Recently i was trying some tricks that i had not done in a very long time. Tricks like matw, toe-bounce, lipstall and i was surprised that i could still do them easily.
Of course these are very easy tricks so it is hard to forget the technique (or easy to re-learn), but i was still kinda surprised.
It is summer and I already forgot all my school-work i learned only a month ago

but i don't forget fs tricks.
So do you think it is possible to forget a trick technique after learning it?
