buzz off people.
go get a hotel room or find your own little hole to PDA in. the general population has just as much right as you to that space in our cluttered school. but simply because you're fine with PDA-ing does not mean that we are. for your information, if you hadn't already known, it makes other people (that means anyone outside of the couple) extremely irritated incredibly uncomfortable.
baby talk especially makes people want to smack you with the heaviest object they have in their possession. next worst on the list is whining.
it doesn't mean that being attached means you have to be literally and physically attached to your other half for the majority of your waking hours. for one, looking like a lost puppy when your other half's not around is extremely pathetic. it gets worse when you abandon the friends who accompany you once your other half is back. it seems as though your friends are merely spare tires for your convenience. you may not mean it, but it sure feels/seems that way.
being in a relationship does not mean you have spend all your time and attention on your other half. i know many a couple who are perfectly blissful even though they don't stick to each other like a fish and its water. i also know couples who manage to communicate without using a single word of baby talk. their communication is far more successful, i do believe. and there are plenty of ways to show your affection for each other without PDA-ing.
by the way, friends do know when to make themselves scarce. if you want solidarity, by all means ask and it will be given. for heaven's sake, friends DO NOT FREAKING want to be lampposts. they feel uncomfortable as lampposts. they'd even thank you for liberating them from your PDA session. so no, letting your friend walk alone is not a sign of abandonment, it is liberation. oh, if there happens to be mis-communication, i wonder if it's because you're too preoccupied with your other half.
I'd rather walk alone then spend my time with two lovebirds who only have eyes/time/attention for the other half. I'm not that desperate. neither do i want to be a spare tire.
my dear laogong would probably say I'm a bitter old woman again, but I'm sure she'd agree with most of the points (most of them were from her to begin with =P). right laogong? ^^
