Tell her the truth, you screwed up.
Hey i need some help. I was supposed to go to school today, but skipped and went to my dad's house since he isn't home. The problem is; I don't know what to tell my mom when she finds out that I skipped school. What do I tell her? Please help
If you had a reason as you said in the Chat section, then just tell your Mom that reason. The truth always works the best and I'm sure if your reason was a good one then there shouldn't be any problems. Capisce'?
