I have been here for a while now and made a few posts. Without knowing my background, I realize it makes it hard for some of you to respond as you don't know what level of understanding, education I have.
My real name is Tom and I am a retired Firefighter from Canada. Pugdaddy comes form the fact that I breed Pugs. I was a Firefighter for 30 years and retired a couple of years ago. I did not go to University. I have regretting the lack of formal education, but not the decision to be a Firefighter as it was a very rewarding career.
I have taken courses in Calculus and finite mathematics and have watch many lectures on the internet. I certainly am not an expert, but I am learning. Hopefully I can continue to learn through this forum. Thanks everyone for patience in my learning experience.
