To reiterate previous posters, yes she is quite insecure. That’s why she rambles on this way. I’ve known a plethora of these types throughout my life. I found that talking to them about their constant bragging is useless. It only feeds their voracious need for attention and validation. Pathetic, they are, with their constant need to be stroked.

What I found works is not feeding them (sort of like you do with online trolls!). When these insecure narcissists start yammering on, just say uh huh and change the subject. Don’t get angry or argue - it only inflames the situation. Whatever she starts dissing (your job or whatever), DO NOT TAKE THE BAIT!

Finally, ask yourself, do I really want this annoying person in my life?

And for anyone who works with one of these motormouths, of course escaping them is not so easy. I worked with one of these types for years. He annoyed everyone. He never got the message in his swelled head to STFU. Best I could do is keep my distance and try not to LOL when the boss got tired of it and let him have it!
