We moved into a new house, (some 10 years ago,) and we had a 3-piece suite. We put the 2 armchairs side by side, (along one wall,) and the couch along another wall. In the previous house, the armchairs were 3-4 feet away from each other, with a stereo in the middle (in a cabinet.)
In the new house, it was not possible to put them 3-4 feet apart,, because of the design of the lounge. So we had to sit the armchairs side by side, with no 3-4 foot -gap. (Just a gap of a couple of inches.) DH sat on the chair to to my left.
He sat on the chair, facing me slightly (and in the direction of the TV,) and EVERY. FUCKING. DAY! he put his feet up on the right arm of his chair, but it hung over the (left) arm of MY chair. His feet were literally 10 to 12 inches from my FACE, with either his sweaty socks under my nose, OR his fucking bare feet.
I kept saying 'PLEASE move your feet!' He would say (begrudgingly) 'where am I meant to put them?' I said 'how about on the pissing floor?!!' 'But I am comfortable with them hanging over the arm!' he retorted. He also said he could not point them in the other direction because he would not be facing the TV then!
It pissed me off so much, that when I got my first laptop (back around 2011, and about a year and a half after we moved in, (and after about a year and a half of tolerating this,) I started putting my laptop on the left arm of my chair when I was using it.
THAT stopped him putting his feet over the left arm of my chair. He got so annoyed though, and kept asking me when I would be done, so he could put his feet up, as he was 'uncomfortable' with his feet down. I just stayed on the laptop for ages (to stop him!)
When I DID finish what I was doing on the laptop, and put it on the floor at the side of me, his feet were in my face within SECONDS! Straight up onto the right arm of his chair they went, (and hanging over the left arm of my chair!) 
Anyway, after 3 years in that house, we moved again, and had a lounge (in the next house,) where we could have the armchairs apart again. THANK FUCK! They are 10 feet apart now. BLISS!
What is it with men, wanting to invade your personal space?
He could literally see NOTHING wrong with his fucking FEET being 10-12 inches from my FACE.
