I have had a shocking fathers day, No one in my family even mentioned it to me until I said can you all be quiet so I ring my own dad to wish him a happy fathers day. 
My eldest son hasn't even said a word to me about it yet.
All my my kids have just argued like cats & dogs all day.
I didn't even get a card. 
It all just tells me I must be a crappy dad.
I will remind then all when it comes time for me to give them their birthday presents on their birthdays, they will just have to wait an extra half a day before they get their birthday gifts.

I hope all you other dads out there have had a better day than I have had.
