Can a person be defined by his/her socks?
   Unlikely I would think, but open to persuasion.

What are your favourite and less favourite socks?
   Medium weight wool with nylon to improve wear, dark navy blue ankle socks. I buy 'em about 3 pairs at a time, depending on bargains available when I'm in the mood (and place) to buy, maybe annually. I dislike cottons, 100% synthetics, and socks with toes. As I no longer dance I don't need white knee-socks any more. Old ski socks fill my boot-sock needs, doubt if I'll ever need to buy any more.

How old are your socks?
   No real idea, my buying method means I have some I imagine may be about 20 years old, but I couldn't prove it. Mostly rather less. Some of the ski-socks will be even older.

Do you save the one-sock-not-lost (if so, for how long)?
   Never have more than one odd sock. Either another vanishes (or wears out) or the missing one sneaks back, having realised the error of its ways. This may take a month or a year, I don't care, as long as there are enough socks in the drawer they can please themselves.

Do you have an alternate use for a lone sock?
   Key/coin bag when indulging in watery activities.

Do you wear wool socks, sport socks, diabetic socks, bed socks,
designer socks, knee high socks, designer socks?
   Wool yes, rest no.

Do some socks "annoy" you?
   Any kind of 'sock-based fashion statement' is well on its way to raising my ire. I view them as almost entirely a functional garment. (Almost, because I have fond memories of a spell in the 70's when some very good female legs were enhanced by thigh-high brightly coloured socks. Unfortunately not all were as good, but you can't have an omelette without breaking eggs)

Are you guilty of sock "faux pas" in public?
   I repeatedly wear unmatched (by knit) socks, but if I can hardly tell them apart when holding them by a window I doubt that any one catching a glimpse of them in situ is any the wiser. I don't wear socks with sandals.

Are you annoyed by any sock faux pas (knee high white or black socks with with snow-white sneakers?
   Annoyed, no. I merely lament the fate of a species that so lacks my exquisite good taste. (Ah, come on, everyone needs somebody to despise.)
