Sorry for your loss John, I understand how you feel. I loss my Dad 20 years ago last week :'(
In years gone by I forgot (busy at work) and didn't remember till about a week later.....pissed me off so this year so I called in and told the boss I wasn't coming in today....or ever on that day. Had a good chat with my brother and talked of doing at least once a year Riding, fishing etc...a brother weekend which would be cool.
Cheers to your old man
Chris
