Me: Rats. We forgot to spray the [pear tree with brown-spotted pears] tree again.
SH: It's your fault.
Me: Why is it my fault?
SH: Because you didn't nag me.
Me: I thought I wasn't supposed to nag you.
SH: You're supposed to nag me on something like this where I was going to do it but I forgot.
Me: When am I not supposed to nag you?
SH: To do the 1040X.
Me: You mean I can nag you about something that takes ten minutes to do but not about something that would bring us one thousand dollars?
