W:Are you OK,John?
M:Yeah,just clearing out this cupboard,Emily.It's full of old junk.

W:Interesting.
M:Ooh,this is the microphone I recorded my first masterpiece with.Bit dusty.I wonder if it still works.Or maybe I should sell it.Who would buy it?
W:Why don't you freecycle it?
M:Oh,that's a good idea. I can exchange a microphone for a bicycle,right?
W:No.You give it away.You give it to someone for free. It's another way of recycling.There are websites that help match you to people who want these things.
M:Free…recycle.Freecycle.Yes,I like the idea. But I would like a free bicycle even more!
