How to impress someone?

listen to them and listen carefully as in pay attention

Play Bach Sonata No 1, Presto on Violin at double speed 😎 it ALWAYS impresses the ladies.

Am very poor at impressing others

Be honest and funny. DO NOT LIE to impress people they will hate you.

Roll you’re tongue
If you can do that

build them a mansion and serenade them

be attractive..... dont do stupid shit..... try not to smell like butt crack
