wait for the moment

If you like a guy and you think he likes you dont awsume and be like "oh i like you" talk to him get to know him.......If he flirts with you flirt back and if theres a pizza place or somthing near you school ask him what hes doing at lunch if he says nothing or he dosent know be like "would you like to come grab a slice with me" .....If he says im doing this(insert what hes doing here)he'll most likely ask why ...so be like "well i was going to ask if you wanted to grab a piece of pizza with me..but if your busy thats cool" .. if he likes you he will most likly figure out a way to cancel his plans and go with you or he will say "oh well we could go this day" or something
