Married couples don't seem to show any affection to each other. However, when a couple is dating, they will hold hands. It all stops after the wedding.
Actually it seems to me to be a matter of the right place and time. I doubt you would find a lot of cooing in the pews of any church at their services. Mature people don't have to 'display' in the public forum to be in love, do they?
I'm with AK - Jeff on this one, I think there's a time and a place for showing affection.
Now, I'm not a JW, but if I was in church with my boyfriend, I most certainly not be showing any affection beyond sitting next to him, just because a house of worship doesn't seem like the most appropriate place to show affection. That sort of thing is best kept to more appropriate places, not churches. I just think that it would be disrespectful to do that sort of thing in church - after all, you're supposed to be worshipping God and giving Him your attention, not canoodling with your significant other.
And for me, I'm way too shy to be all lovey-dovey in public, anyway - I don't do anything besides holding hands when I'm out with my boyfriend, and maybe a quick kiss on the cheek. After all, what if someone I know saw us!! I'd die of embarrassment!!
As for JW couples, I can't say anything about what it's like inside a KH, I've never been inside one before, but I can speak for one JW couple that I know. My boyfriend's parents have both been JWs their entire lives and they've been married for nearly 32 years, and they still act like lovey-dovey teenagers together. They tease each other and play with each other and giggle and smile a lot and just look really happy together. They even still shower together every single morning before work. They're definitely very much so in love, it's kinda nice to see a married couple like that.
My boyfriend mentioned once that if I ever went to the KH with him (ooo, just the thought scares me, though I did say that I'd go with him if he asked - luckily, he never goes on his own and I certainly won't be asking to go, that's for sure!!), we wouldn't be able to give any sign of being a couple and he'd have to introduce me as his "friend", not his "girlfriend". I don't think he's ashamed of me, he's already introduced me to his parents and siblings and they all know that I'm not a JW, but they accept me anyway, but I do think that he's concerned about his image in his congregation. After all, a "good JW" doesn't date "unbelievers" and certainly doesn't express any affection for them, especially not in the KH.
Just some observations.
