Flip flops, havaianas, thongs

A day of marking and as I was doing it. I went through my flip flop collection (and sometimes had to listen to tests twice as a result, not very efficient!), and these ones here are, sadly, going out the door. They're either a bit too small for me now (my feet have spread I think!) or they have the slim straps, which I can't walk in anymore.  Have no fear though, I still have 15 pairs!  These may be taken by a neighbour and if not will go to the recycling centre. I suppose I could sell them on Wallapop if the neighbour doesn't want them. But can I be bothered?  And wouldn't it be better if somebody could use them that couldn't afford to buy them?
