im goin out with this guy and im not supose to he wants to take me to the 映画 got any ideas on how to sneak it past my family?

here is an idea:just tell them the truth.
That way あなた don't risk getting caught and get in trouble.

Get some フレンズ involved! Tell your parents what your going to the 映画 with some friends, and if they don't believe you, get your フレンズ to "confirm" that their going. I SHOULD work!

just tell ur parents that u r going with ur friend and then when they drop u off and shes not there just say she was running late and when ur parents pick u up say she had to leave early because she needed to study
idk if this will help または not but good luck:)

yeah...don't go

Get your dad to take あなた then in the middle of the movie say あなた dont feel good, and your going to the bathroom. He cant follow you, cuz hes your dad, then sneak into the movie your bf is in.
