Cell phone rage

On Friday I got a phone number local to Vancouver. This meant I had to give up my previous phone number that I had had for 21 years.
Today, I was told by some friends that I didn’t need to do that. A friend of a friend had moved from Edmonton to Vancouver and kept her number. Well, I really liked my old number, so I never wanted to give it up. I was upset that the cell phone person I was dealing with had never even mentioned this as an option.
I went back to the cell phone dealership. Everything is conveniently within walking distance, so it wasn’t hard. There I found out that my old phone number has already been claimed.
Yesterday I was fine with losing my cell phone number. It was something out of my control, and it made a sort of sense. Now I am angry that I didn’t need to. And yet nothing has changed. There is nothing I can do anymore about it, so I should move on.
But I am also suspecting I would have had to change it anyway. In a way, it is just a number, so I wouldn’t think that any number had to be tied to a particular location anymore. But there is such a thing as being able to tell the location of a number by looking at the first few digits.
