What do you do when your in fourth grade and the girl that you like likes someone else?

Key tip in relationships is patience, but in 4th grade, just a little warning, it probably won't last long, most young relationships don't, but you should go up and beyond the other boy/girl, so like if she drops something, pick it up and stuff, show that you like her, and if you think is the time to ask her out, don't shy away, if she says no you can learn, if she says yes your golden.
