Which one is correct

oh my goodness, really?

My mom and I ate at MacDons is the closest one to be grammatically correct but one minor problem. MacDons is slang for mc Donald's which makes it incorrect as well.

These are how they should be written out.

You're so pretty. Their kissing. My mom and I ate at Mc Donalds. Your bike is at my house.

@Max powers we might just know that.

@Max powers btw it's they're kissing cause their means you own them
