There is no couth anymore. People advertise wanting something. You respond with what you have. Most don't even have the decency to answer you back with an answer either way. Some you have to make several attempts to reach them and get an answer. Very upsetting to another buyer, whom you put off because of waiting for an answer, along with your self if it causes a lost sale. Guess I'm just old school. Was raised with manners and respect. Am I out of line, and should just accept this is the "new modern" way of things.
