My wife refused to clean our windows because it a lot of work - you have to clean the surrounding areas first, then you can proceed to clean the windows, and that’s hard to do with two children around all day, she said.

It took me 4 hours, one baby slept troughout the whole process and the other one was a bit too keen to help, but we managed.

She hasn’t spoken for two days straight with me, but then she finally admited that I was right. There was no dispute about windows since. :)
