That was really sweet. Maybe a bit sappy, but I liked how you used a simple thing like a Christmas card to convey all that emotion. Loved the bit where the three tried to give him a toilet seat. It reminded me of Harry's own not unfrequent hospital visits. Well done.
This is very well-written, and the parallel between the two cards was very nifty. Your characters were perfectly incharacter, or at least I assume so. They're how I imagine them. Very nice. I wish I could tell you more, but I'm falling short tonight. 10/10 most definately. Cheers~
