One of my all-time favorite tv/film characters is Onslow from Keeping up Appearances. I think one of the reasons I like him so much is that the actor who played him, Geoffrey Hughes, is an absolutely adorable soul.
Here's Geoffrey's being interviewed about a year and a half ago, and I think a lot of what I admire about him really shines through here. he is good-natured, empathetic and predisposed to look kindly upon those around him.
Geoffrey's is in hospital and my heart goes out to him and all his dear ones. I think he's a rarity in that he's one of those people who can't hide what a big-hearted person they are. It's one thing to pretend to be grumpy, persnickety characters, but in the end, you can't hide when you're a loveable old softie. :)
