You can get covers for them, so you can practive and they wont be loud
and when they're out you could play them without the covers
but generally when parents think they're too loud it's hard trying to convince them otherwise
Bribery could work though lol
But of you havn't had drum lessons before or can't read music
you're probably best off not buying them until you can do either because you will grow out of it and get bored
Sure it's fun to hit the drums and try and make beats, but yeaahh you're better off knowing what you're doing before spending hundreds on a drum kit
