Cath wants to keep them with her in Reading.

This is perfectly fair - after all, I get them most weekends. Cath needs some weekends to do stuff with them too. She has them during the week, of course, but during that time they are always rushing about, getting ready for school, or bed, or whatever. At the weekend, there is time to do stuff, and I'm lucky enough to get the lions share of that. Can't complain, can I?

But I still hate it. I never know what to do with myself at the weekend when I'm on my own.

I guess that I'll just have to get very drunk.
