So one week I set everything up for the wrong time, another week I set it to the wrong channel, forgot to turn something on another week, and so on. "Oops, my bad. I'm sorry, we'll just get it again next time....". Eventually, I didn't hear any more about it. :-)
That’s called being passive-aggressive, and it can kill a relationship.
It’s much better to just be honest and tell her that you’re not interested in such drivel, without being a jerk about it.
If she’s the type to get upset with your honesty then she has a problem too, one that can also kill a relationship.
