Yay, my h replied that he'd checked the bank account and unfortunately his £200 hasn't gone in yet (hmmm, I'm not commenting :-) but that he has rung up and extended the overdraft so we won't get charged.
This is the first time ever he has helped, but then it is the first time ever that I have asked, and also the first time that I gave him the chance to do something and didn't snap 3 hours ago and said that I'd sorted it!
Has anyone got any ideas about how I can thank him without sounding patronising but at the same time reinforcing that he has done good and I really appreciate it?
