The idea that you have to and/or CAN reply in short order is bull. Just because the capability is there does not make it a requirement or that everyone is able to.
Do you always reply immediately to your phone going off? Do you have anything that takes precedence over your phone or does it dictate your schedule?
Here's another example of why I don't openly post my phone number on the forum, only given thru PM. It keeps spammers and guests from seeing it and having multiple contacts on a single ad can be "interesting" for potential buyers. Let's hold off until the OP can either comment or post SOLD.
