J.S.
See this just does not make sense to me at all. Son calls you, so he knows, saying she made these plans so you can't see him. Then she calls you because he was upset with her, but he would have been upset with her before he called you so that doesn't make any sense.
He called you the day before, ya know?
Plus as a mother of teens and adult, at 15 you can't stop a kid from making phone calls. So either this is all BS and you are trolling or you are completely misreading what you think is going on.
