Little kisses and holding hands is ok. But practically making out in public, is taking it to a whole other level that's not acceptable.. My hubby and i do hold hands and kiss in public. Little quick pecks, not long drawn out kisses. But anything else is saved for the privacy of our home. It's disrespectful to other people who don't want to see it. Plus i imagine if you're single and unhappy, it's a little like rubbing one's nose in it.
