Stuck on you..

I've always had a problem with PDA ( for the non-enlightened ones, it's short for public display of affection), especially when I know the person engaging in it. It somehow makes me uncomfortable being around them. I feel like a 'tiang' so to speak, an unwanted object of obstruction that's getting in the way some hot lurrvving.
Call me conventional,old-fashioned.. I don't mind..Holding hands is okay, I guess. So is the occasional peck on the cheek or forehead. More than that, I'd say "get a room,people!".
Maybe I'm being selfish; not wanting to feel akward. But aren't they selfish as well, to disregard the comfort of others around and sometimes got to the point of being rude? More so if the people they're with happen to be single and looking?
What are you supposed to feel when a bunch of you agree to go out as a group and within this group, 2 lovebirds isolate themselves by walking far behind, or do the MIA thingy?
I mean, if you wanted to go on a date alone then bloody hell tell us, dont make us feel embarassed and uneasy. It's just not right.
But it's not so bad when you're out with couples, coz you sorta know that they've got their partners eyes to gaze into while you're at it...given that they're mellow.
Not the kinds who lean against the banisters in shopping complexes, engulfed in each others arms and threatening the lives of those walking about downstairs...
How do you hold a conversation with someone who's playing footsie under the table? Or playing with their partner's hair? Or meraba-ing their thighs?
These mobile parts of our anatomy do not have a mind of their own. They're all connected to the main CPU, our brain.
So when I'm talking to someone who is busy groping, I know that I dont have him 100%. That the other part of him has wandered off somewhere. Where? I don't wanna go there.
So, whats the point?
I pointed this out to a friend and he said I was just jealous. That I wanted someone to hold and kiss and whatever..So NOT true!
Of course I get lonely,everyone does. But that's not the point. You DO NOT make the people that matter feel akward.
I don't know how men think, or maybe I'm just too sensitive to others' feelings (here we go again), but ask my ex and he'll tell you that i've made it crystal clear that between my friends and him, my friends come first. That could've been one of the reasons why he's my ex. Oh, well....
But he eventually came to terms with that and respected my wishes, though I knew he was disturbed by it at times.It's not that I'm embarassed to show the world my love for him. If he's matured enough, he'll know what he means to me without needing to tongue-wrestle in public. Isn't it supposed to be just between us?
Hearing laments of "I want a boyfriend" and "So nice,you got boyfriend" has reinforced this, coz i know that when people get all mushy and lovey-dovey in front of the lamenters, it'll send them a pang of 'if onlys'.
The reason I've always stressed this is that right till the end, your friends will (almost) always be your friends, but partners? More often that not, no.
Ultimately, it boils down to having respect and regard for the people around you. If we're gonna behave like lustful animals in public, I guess it doesn't take much to understand the term 'uncivilised'..
