First and foremost i would grab my video camera and record special messages for my children. For their important birthdays weddings etc.
I would also buy gifts for those specific occassion for each of my children!
Next I would spend all of my time with my children. Taking them to all the places we have dreamed of going and allowing them to stay up late while I read them the great novels that I had always wanted to.
Late at night I would be with my husband and always be loving towards him. Even if he made me angry I would simply say I love you and leave it as such.
Last I would rob the richest bank on earth. I would hide the cash and let my husband divide it up amongst my children, that way I can leave the world knowing that they are ok.
