SH: Look! He wrote "their" instead of "they're."
Me: Whatever. Don't be like your dad.
SH: 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.
SH: You made a mistake in that spreadsheet you want me to print.
Me: What are you talking about?
SH: You said to meet at "the Smith's" for the block party instead of at "the Smiths'."
Me: Big deal.
SH: My friend Doug thanks me when I correct his mistakes.
Me: I do not thank you. I am not asking.
SH: But you married me. You knew what you were getting. And now you're one of us.
Me: No I'm not.
SH: Is that one of the reasons you wish you hadn't changed your last name?
