This thread is making me chuckle aloud!
One of my families had a little boy who as the absolute image of my own youngest son! He was a prem baby (22 years ago!), has a funny little flat head and wears specs, just like the child in my virtual family - of course I had to re-name him 'Chrissie'!
Sadly, his 'parents' died when he was 17, he mooched around the house, depressed for a while (cheered up a little when I gave him sweets!) then went off to college leaving the house empty.
Poor little orphan Chrissie quite brought a lump to my throat!
