I am sorry you are not feeling well. It is great that your daughters still got to go to the CNE. It is always so much fun. With your wife in such a pissy mood - you were better off to not be there - who needs that?
My suggestion for the future (for what it's worth) is to make plans to take them on your own next year. Let wife do what she wants with them and you do the same. If she acts like that when you're around - it diminishes the experience for the girls.
And your girls are both sweet & thoughtful to get you something. My ex, as you know - is the ex from Hell but I do not EVER say anything öff colour"if my kids choose to buy him something. He is their father. And who am I to interfere with their R and their rights?
Hope your cold is better today. I suggest cough syrup over the cookies. I made some yesterday that were really good. Maybe you can have one of those. YUM!
