I have three items of furniture that I no longer have room for, so I put them on Freecycle. I got an immediate deluge of emails from people saying that they wanted them. I picked three, arranged a time for them to collect - and NONE of them have shown up! I have been waiting in all day. 
I wouldn't mind if they changed their mind - I could then offer the item to someone else. It's the fact that none of them have even bothered to call or email to let me know!! I am feeling grumpy today, so maybe I am being uptight... but it just feels a wee bit rude. AIBU?
Also, what do I do now - how long do I wait before offering them to other people?
