don't apologise Lisa.grandparents often are very special people in our lives,especially as we are growing up.They have time to play,and teach us stuff,they put up with our naughtiness and later our bad taste in music and fashion and become our advisors when we need adult input but can't talk to our parents for whatever reason at the time.So of course we are going to miss them no matter what age they get too we still don't want to lose them.
I hope Brad is better soon so you can get some sleep.
