Very sorry about your dad man, this makes me feel pretty crappy and did ever since you mentioned it to me a little while ago..take care of your family,cherish the memories you had with him together with your family and friends.
My father will be visiting me from NL this week, i will most definitely be hugging him just a little longer each time i get the chance within this short amount of time i will have with him because every moment we spend together is precious time that can't be wasted, you just never know, almost lost him to a heart attack last year.
