That is v confusing
I have 1 sister, we share the same mum but different dad.
I have 1 step-brother.
See I'm not confusing
Charleys dad reminds me of my grandad!
My grandad had 8 children to his ex-wife, and 2 with my grandma, most of his children called my grandma mum and all came up to the funeral.
But a few yrs back after he had died, my mum was talking to my grandma and it all came out there was another 2 brothers. Then when my grandma died, we were going through her things and we found some of my grandads old stuff too, it came out there was actually another 5 of them out there!!! We all said it'll be like only fools and horses, when they go to france and they all look like uncle arthur! We'll go down london and there'll be a hundred and one clones of grandad walking about all 4 ft!!! So if your small and come from down Andover way, then you could be one of us!!!
