Well my friend, there is only one way to know if a girl likes you. Here is what you have to do. Put some toast in an envelope with her name on it and give said envelope to her. Then wait for up to two days. If she gives you an envelope back..., do not open it until you get home. Get home, open it and there should be nude pics of her inside. The next day talk to her alone after or before school. Then you have to say a secret code, is the peanut butter in the potato? If she answers, No it is in the apple sauce, then she likes you. If she kicks you in the balls and runs away, then it is safe to say she is not interested. Hope that helps

Long story, look it up
