I'd love to come to one but, as I've just voted using the "I dont think I'd fit in" option allow me to explain.
I am actually quite shy when it comes to sitting down for a drink or a meal with complete strangers. For this reason I've missed out on weddings, birthday parties and the like simply because I hate that awkwardness that comes form not having instant familiarity.
If I did turn up I'd likely be the one hiding behind the fruit machine with a bag over my face and if anyone said "Are you Wullie?" I'd probably say "No!" turn bright red and leg it. Its a pity because I'm quite an affable bloke but crushingly shy when it comes to strangers.
Ah'm away back into ma cave noo!!!
