It may be no wonder as to why I've never had a really close friend, either M or F, let alone having a partner - and it's highly unlikely that I ever will have one, though I'm not closing off the possibility for evermore.
I've never been able to abide noisy eaters. In my 'living-in-a-bubble' life this irritation comes to the fore frequently in trains. Sometimes I just want to yell out when a nearby passenger tucks interminably into a packet, or packets, of crisps (potato chips in U.S.) It's so damned disruptively distracting. Eating apples is almost as bad. I think such practices ought to be permitted only in private, either individually or with co-consumers. I direct almost the same level of 'aaaaaaargh!' at mobile phone users who seem to insist that their side of the conversation must be heard by every single person in their carriage. Why? One doesn't (usually) hear every word of a direct conversation going on at the far end of the same carriage, at least not with the same regularity. Why do phone-users have to raise their voices so? (I take heart in knowing that in this case at least there is a substantial numberof people who are on my side.)
Talking of travelling on trains, I also can't abide those slovenly and uncaring passengers who place their shod feet on the seat opposite. Doesn't it even cross their parochial little minds that another passenger is inevitably going to have to sit directly down on the street-dirt that the offending person has brought in on the soles of their shoes? One sees the same practice in cinemas and theatres with certain, usually younger, members of the audience draping their entire lower legs over a vacant seat in front of them, again resulting in their dirty shoes coming in contact with the seat-fabric. It's so ill-mannered! This unsavoury behaviour only started to happen within the last 2 or 3 decades but now it's omni-present. I don't mind in the least if a train passenger first removes his/her shoes. Just simply placing a newspaper on the seat opposite indicates some degree of forethought and care, but seeing such is so rare.
I was going to go on with several more pet peeves but just reading what I've written above I seem to be coming over as a cantankerous, intolerant, old fart, which may be true ("Things were so much better in my day. But now the world's going to the dogs!") so I'd better call a halt - for the time being. But it may be clearer now as to why I've gone through my life without ever having had an especially close companion. Actually, when I put it down in black-and-white it's becoming clearer to me.
