I think my washing machine is eating my socks !!!!

Why am I always having loads of odd socks?

 

I am constantly buying socks, (and yes i always buy pairs!!!), but regardless of how many i buy I am always left ( or right lol ) with a dozen or so odd ones.....

I Keep telling myself its not possible...how can this be ??? 
I'm sure I put pairs in the washing machine but by the time they come out...theres half missing!!!

So does this happen to you too....???
