That thing where you put on a fresh pair of socks and one has a hole so you think well I went to all that trouble to pull it on, this will be your last day little buddy, I’ll just throw it away after I wear it today.
Last chance underwear happen now and again as well but I guess it depends on where the hole is.
If it’s so consistent, I’d just buy an extra pair of the large ones.
That’ll outlive the small ones as well. I usually just buy the same amount of large and small socks and usually at least 2 pair of each, so I end p up with 4+ of the same sets. They’ll dwindle down to 1 pair in the end. One ship is even so nice to put the size in the socks, 39-42 in yellow and 43-46 in blue. (there is even a cheap shop that does the same, but those sock don’t match, 39-42 with horizondal lines and 43-46 with vertical lines… why would those need sizes in them ;) )
