I've see this come up a few times and it bothers me. I'm a little bit of a grammar nazi, and I apologize. ...
Perhaps, when one is being a grammar Nazi, one should know how to conjugate a verb. Nothing takes away your "expert authority" faster then making an error on the second word of your post, in the same area you're presuming to lecture others on.
When communicating using the first person singular, the present perfect form of the verb "to see" is "have seen".
Agreed, and fixed. It mostly happens because of the phone typing. I would like to note that I did use the correct verb though.
I'm on this boat with you, just because I know the difference doesn't mean my stupid smartphone does.
