I'm in love with Godric. I never knew of this condition and Charley is such an inspiration!
I can tell you that Lucy knows how to get out of the way when she feels threatened (meaning feet walking around her, the cats playing too rough, etc). Hopefully Alastor will learn to do the same. I don't know, people likely think I'm crazy but I would like to think that Alastor knows Godric means him no harm and would rather be bowled over than be without his special friend
