That story about your Dad was a great one! As Kim said, you are so lucky to have those happy memories and stories to share with your Dad.
My mother was abusive, and I didn't meet my Dad until I was 35, so I don't have those warm, fuzzy memories. You are very lucky.
Let him know that we are all thinking good thoughts for him on Tuesday, and that we'll let him be an honorary member of our brain fog club!
Take care of yourself.
