Being competitive

Is this a narc trait? Mine was so competitive with me. In fact the first thing he ever said to me was when he saw me at school with a camera around my neck & said "is that better than the Canon XYZ" (it was).

I bought a car, he bought one a month later.

He emailed to ask what camera I had, then bought the next model up.

I've taken up running. He now does the odd 5/10k run. I know it's not impossible, but for somebody who "hates running", it surprises me he can just randomly go out for a quick 5/10k run.

I won a running comp at the gym. The next day he "ran up a mountain".

I said I wanted a camera lens but couldn't afford it, he bought it.

It goes on and on and on. Is that what they do, or is it specific to him?
