my own dad has just died in the last 2 weeks, 18 months ago he was told he had 2 months left, it was hard for all of us as myself and my mum cared for him, yes at times he was a pain, and yes at times i was mean back to him, but at the end of the day you dont know how long any of us are going to be around, so be nice to him and everyone else around you, you will need them one day, its hard but at least at the end of the day you can say, i did what i could for my dad, you only get 1 dad and mum, make the most of them, treat people how you would want them to treat you, its easier to smile then frown, make the most of um while they are still around, you will miss um so much when they are gone, and its no good thinking then, why didnt i do this or be nicer to um,
