Men have been continuously hounded by one question--how can I impress a girl? This is understandable to a certain extent since every woman is a different individual. Every individual is entitled to an opinion and a personal way of evaluating things. This means there are no standard rules for impressing a girl.
The most common apprehension among women who want to ask a guy out in person is if their approach is going to make them appear too forward or aggressive. This is just a misconception. Most guys love the idea of being asked out by a lady. In fact, this is perhaps the biggest compliment you could ever give a guy.
