Talk about the sports he plays or watches, also tell him what you like to play or even ask him if he could teach you how to play one of his sports of interest.
It completely depends on the individual boy and what impresses him.It also depends on what you mean by "impress". You being yourself should be enough to impress a boy, if that doesn't impress him then he's not worth trying to impress.
Be yourself.
get anarexic
be hot and romantic
be yourself
be yourself,and tell him exactly how you feel,, thatl impress him.
Of course not. 10 year old girls shouldn't do ANYTHING to impress a boy.
you flirt with him or dress to impress
You don't do it by trying to.
just be your self
Well if you are going to impress a boy you should wear something reAlly nIce and make eye contact with him.and why not give him a smile(:
okay well im a girl myself. and for me a boy would impress me by playing sports and kindve showing off a little being tough around his friend but not to the point where he acts fake and really isn't tough but just act like yourself that's one of the main things that girls like about a boy is when they act like theirselves and don't fake it at all that's how you can impress a girl.
