SH: So how much will it cost?
Me: She said ten something after the 20% discount.
How many stones? Me: A lot. SH: Let me count.
SH: I thought it was 50%.
SH: Didn't you say the original price was eleven dollars?
Me: Something like that.
SH: But that's not right.
Me: What do you mean?
SH: Eleven dollars with 20% off is way under ten dollars.
Me: Well, taxes or something.
SH: No! Twenty percent of $11 is $2.20, so it should be $9.80!
Me: Whatever. I don't care. It costs what it costs.
SH: But the numbers aren't right.
Me: You call her and give her a math lesson. I don't care.
