Sometimes [read often] wonder why it is that people contact you in answer to an advertisement placed, they sometimes even write a second time, and after you have taken the trouble to send them emails, photographs, addresses, facts etc. you never hear from them again? Very frustrating. Do other Glocalers find this rude? Saying thank you, or sorry it's not for me, takes so little time, costs nothing, and means so much.
At least you know where you stand and can perhaps offer the item to other folks.
