Funny thing is that we were two males and two females in this group and three of us knew each other. (the mostly-roadie was the new one). I don't mind taking advice on while riding, in fact I welcome it. This guy's attitude was just different than I'd encountered before.
Some people feel they always have to be talking. Its almost like the silence makes them nervous or uncomfortable. I suffer from this when doing tech support calls for customers and there is a lul in the talking while we're waiting for something to reboot, changes to take effect or whatever. Some (not me) like to always tell other folks what or how to do it.
Some guys (and girls) don't realize there tone or the way they are putting things to others. Especially, the socially awkward like myself.
Also, some people just don't click.
I would not let it bother you. OR if it really does, figure out how to table it without being like the offender.
JMHO, YMMV....
No matter what, keep riding.
