13 mismatched socks

First load of laundry in my new washing machine, I spend the evening washing, drying etc.  Go to fold and put away, and I end up with 13 mismatched socks.   How can, in one load, the dryer eat that many.  I know, I know, they are probably under the bed or on the bathroom floor, but it doens't bode well on my laundry sorting and doing future does it?
