Unless I have forgotten how to English, you just said that your mother is pizza and beer.
Classy indeed.[/QUOTE]
Why actually, if I may go back to basic English, mind you I haven't had a class in in like 13 years. . .Remember your prepositions. Since "with" is a preposition, you'd have to remove it from the verb/noun part, like so.
(I am) Having Mother's Day dinner (with mom), pizza and beer. We are a classy family.
Or you could read it as I'm having dinner with mom, pizza, and beer, as in 3 parts of the dinner but not actually the dinner course. But I figured the comma and the lack of a comma after pizza would suffice here and get my point across.
BTW, I am not an English teacher at all, which should be 100%
ing obvious. Just clarifying my sentence structure with what little I remember from English classes.
