Should you tell your best friend's brother you like him?
To simply blurt out "I like you" (actually meaning you are
interested in him or love him in most cases) is rather a shocker
and will put the guy on the spot. Spend more time trying to talk
with him so he gets to know you a little better. Perhaps your best
friend will tell his/her brother that you would like to go out with
him. You actually can handle this on your own by simply taking your
time so he gets to know you and if he doesn't ask you out, then you
ask him out.
