How lovely to hear from you! There's no need to apologise at all; we didn't expect that you would be up for entertaining visitors for a while yet. Arthur and I would love to catch up with you sometime this week, if you'd like. Name your date.
As for Ron, I've told him in no uncertain terms that he owes you an apology, at the very least. I'd appreciate it if you'd let me know when he does come by. He played a pivotal role in bringing the war to a close, but your concerns are far from the first that we've had regarding him since the fighting ended. He had promised to speak to someone, though obviously something more is needed. Of all my children, he's the most difficult to approach, and obviously I can't scoop him up and take him to Mungo's as I would have when he was a child. Any advice you have on how this might be handled would be greatly appreciated. If he's threatening you, something is seriously amiss.
Do let us know which evening you'd like me and Arthur to come by. It will be so good to see you again!
