I love this too. The way it was very much a late second chance for them both. Severus was wonderfully snarky and I had tears in my eyes at one point as their story unfolded.
I loved all the little touches too. Harry's friends, the very obvious affection that his children had for him. Harry's unconditional support for Al and Kreacher I loved the tale of Kreacher and the goats that was running in the background!
