It does matter to me who things go to, yes. I think a please and thankyou goes a long way, and it's the least you can do if someone gives you something for free and waits in for you to come and pick it up/invites you into their home etc
Gets to the point where you screen emails before responding to any so you can give the item to someone who asks nicely and deserves it, rather than the knobs who are like "I'll have it, call me to arrange collection"
I'd rather keep the item than give it to some thankless ingrate who would march in my house without so much as a hello. I gave away literally a room full of baby gear- pushchair, highchair, bath, clothes, toys, you name it. The woman who came for it didn't even look at me, or thank me, just shovelled it all into her car and fucked off. Its just rude!
I always make a point of thanking them in the arranging emails, in person when collecting the item, and in an email afterwards. Kindness is what keeps freecycle going, after all.
