Oh God yes - been there, done that.
"Er, hi!" is an absolutely typical greeting from me to strangers when I'm introduced like this, too.
I'm not too fussed about the idea of germs - but some hands are just
disgusting to touch: clammy, sticky (where my hand actually retains this stickiness and I
have to go and wash it off ASAP), squishy, flabby - all generally unpleasant.
So yeah, it's a 'touch' thing with me but I've also always struggled with this plain
weird idea of how grabbing hold of each other's appendages is considered a necessary part of meeting people. Are we checking to see if they'll drop off? Proving there's no concealed dagger?
I mean, we could just as easily hop up & down on one leg a couple of times. That would be every bit as weird and every bit as meaningless - but at least there's no mutual groping.
