Yeah, we have a difficult relationship these days. I feel so bad for getting angry about material stuff, but I don't buy a monitor every day and there is no guarantee he wouldn't do it again.I'm glad to hear it.
And, don't be too hard on kitty, that's their annoying, sadistic way of showing they care.
When I got married, my wife brought her cat along (all my life, I had dogs; this is my first cat), and while she isn't very sociable, she loves to annoy me.
If she wants food, and I ignore her, she climbs up my desk, starts messing with my papers, or goes sharpening her nails on the boxes I have around with Blu-Ray films.
She knows that gets my attention.
For context, I tried going couch gaming for the last few week and kitty decided that the TV was a good scratching post. I'm not as attached to the TV, but still it's painful to watch and I unfortunately can't 'have a talk' with him. And that's without talking about the risk that the TV fall on him.
