If you can, give your Dad a call and tell him how much he means to you. Next time you see him, do the same and give him a big hug.
I don't mean for this to be a pity post but my Dad passed away a week ago this morning and I'm burying him on Monday.
I had a really cool day today getting to see the ins and outs of the business I'm in and I caught myself thinking about how I couldn't wait to get home and tell my Dad about the day I had.
It would have been one of those great conversations where I probably would have found out that my Dad knew things and had experiences in what I did today that I never knew before.
I knew when I got to say my goodbyes that the hardest part would be days like today or days where I was having trouble with my car, the house, the yard, etc. when I wouldn't be able to call him and get his advice.
So, as a favor to me, hug your Dad, give him a call and let him know how much he's meant to you. I promise you won't regret it.
