hey you can never no if the girl likes you unless you do a bit of studying but unless your friend is good at pocking up girls himself i wouldent take his advice you need to see for yourself if she likes you alot of men like to think they no when a woman likes them but after all the pua is all about u not needing to be the best looker in the world get your confidence up and charisma and then worry about you looks have girls ever told you were good looking or oppisate and looked like they ment it chances are if you are you would have been told by now.
