Nowadays it's the opposite. If you walk into a room and only do that sheepish wave, people think you're rude. As if you're too cool to hug, or even immaturely appearing like you don't want to catch others' "germs".
I credit the rise of the single-armed "bro hug" with a lot of modern day greeting expectations. Something we picked up, I suppose, from seeing sports players do it. It starts off almost like a handshake, then you "bring it in" and end up giving them a big, manly cuddle - hips not touching, no more than two seconds of contact, of course.
Then came the "bear hug"; a greeting between men that begins with wide open arms and transitions to an "arrrhh"-type exclamation, as the two of you muse over how long it has been since you last caught up.
Personally, I love the bear hug. I give it to almost everyone. It's welcoming, it's warm, it ensures people know I'm an affable guy - or at least I'm trying to be.
Yet greetings still become problematic, because I don't want to hug or kiss **everyone**.
The other week somebody I didn't even recognise tried to give me a hug, and I was so shocked I pulled away. A hug is also really awkward when you bump into someone on the street, because you're completely unprepared for it (a bear hug, for those who haven't done it, takes up the entire footpath and forces strangers onto the road). When you're leaving a group of people and finish hugging your friends, it's also very clunky to attempt physical contact with your **friends' friends** (i.e. people you only just met two hours ago).
Perhaps the most uncomfortable greeting situations involve those friends who we can call "non-huggers". Rightly so, some people just don't like being touched. They find it invasive. It's hard to keep track of these people, though, and sometimes out of habit you'll try to hug them and be returned only with a "pseudo hug"; a light shoulder-to-shoulder grip that feels as bunglesome as it does eerily long.
There's definitely a need for some modern-day hugging etiquette for us poor Kiwis. We're not used to this whole physical contact thing - Fred Dagg never had to give anybody a hug, did he?
I hope we find ways to navigate this greetings minefield. Otherwise, we'll soon end up with a Euro-like model that sees our days consumed by multiple cheek-kissing every time we greet and leave anybody we've ever met before.
