Bragging is such a vile trait in a man.
We had a tradesman come to our house the other week to do a certain job in our house, and he spend the ENTIRE hour he was there, bragging about his new house he and his girlfriend are having built, his new merc, his inheritance of the low six figures (think £300K he said!) the 3 homes he rents out, his trip to New Zealand and the far east he has coming up (for which he is taking unpaid leave of 6 weeks which he can afford obviously!) and his boat he keeps in the harbour an hour's drive away.
Utterly boring and annoying and I did think 'if you are THAT RICH, then why are you doing this job?'
Also, when I was a young adult single, living in London, I was getting the train back from home (where I had been visiting for the weekend for my dad's birthday,) and a man came and sat by me, 24-ish, very good looking, smelt nice, and seemed quite appealing.
He said he was a submariner, and proceeded to yabber on about himself and his mates and his flash Porsche and his £300K London apartment (this was the late 1980's so the equivalent of that is about a million now!) and all the countries he has been to.
At no point did he ask a THING about me in the half hour he was gasbagging. Not my name, or where I was from, or what I did for a job, or if I was at uni - nothing!
So after about three quarters of an hour (that felt more like half a day coz I was so bored!) I said 'I need the loo' and grabbed my backpack, and fucked off to another carriage, waaaaay down the train.
He clearly wanted to impress me, and it was probably some kind of 'flirting' (in his mind!) But fuck me, he was SOOOOOOOOOOOO boring.
Oh and the answer to the question is I am NOT impressed by men bragging. (or women for that matter!) It's obnoxious and it bores me.
Pretty sure most women will say the same.
