Here's a scene from last week's recess on the playground while I was subbing
Melanie (1st grader) is sitting alone, building mountains with the rock/sand/dirt.
Anna approaches Melanie, skipping.
Anna: "Can I play with you?"
Melanie: "Sure. you can build another mountain."
Anna: "ok."
1 minute later
Anna: "do you want to be my friend?"
Melanie (smiling): "yea. sure."
