Primo: Look! He wrote "their" instead of "they're."
Me: Whatever. Don't be like your dad.
Primo: What do you mean?
Me: I mean don't be petty, mean, and didactic over a Facebook posting. It's not formal writing. It doesn't matter.
Primo: You made a mistake in that spreadsheet you want me to print. You said to meet at "the Smith's" for the block party instead of at "the Smiths'."
Me: Big deal.
Primo: My friend Doug thanks me when I correct his mistakes.
Me: I do not thank you. I am not asking.
Primo: But you are going to marry me. You're going to be one of us.
Me: No I'm not. I mean, I will marry you, but I will not be one of you.
