How to get away with going to a party thats at 11pm?

So I'm 16 and my mom is definetly strict but i have gotten a way with a FEW things very little. She even tracks my iphone. And i was going to ask her to bring me to a birthday prty for someone from work she wouldnt even suspect we would drink or smoke bc she usully doesn't BUT she would not let me leave to a party at 11 she'd prob know what's up so even if i say "its a sleepover" i'm still gonna have to end up leaving at 11ish so she wouldnt let me, so i've gotten caught sneaking out before like she see's me missing lmao

"So I'm 16…"

Don't go. Be a kid while you still are a kid, worry about being an adult when you get there.

You don't even know how to spell 'but'
