My wife has about twenty pairs of socks, and no more than a few of the pairs are the same variety. It&#x27;s like some masochistic combinatorics problem every single time I fold socks.  My kid and I literally were playing &quot;sock go fish&quot; a few times to get him to help (except ... I was more interested in the pairing, rather than taking turns. Doh.)<p>Laundry-folding happiness is increased significantly when I don&#x27;t have to play &quot;Find-the-mate&quot; every time I pick up a sock (which applies to my kids&#x27; socks as well, since they are all patterned, but thankfully my son likes wearing party-colored socks, so I only need to match on shape).<p>I have two &quot;vintages&quot; of socks -- the old ones that I hate, and the newer ones that I prefer, roughly equally divided.  I would donate + re-buy if I had more than two flavors of socks.
