I have to say that I have used a majority of those "excuses" as you call them when speaking with overly pushing dominates. At least I did when I was younger and less experienced. I didn't want to "offend" anyone and wanted everyone happy (subbie here after all... natural trait in some ways!) But, after going through MORE then one Dominate who seemed to be all that and sliced bread too only to quickly discover that what they claim and what they were are completely opposites I have changed considerably. Now I will clearly tell them I'm not interested... and yes, basically in them! The approach makes all the difference and if anyone thinks that a sub should be instantly willing to play (or even cyber) and especially meet after only a few moments or a few assorted conversations with someone then they are seriously mistaken. Trust has to be developed and while an internet context helps to enlarge the circle of people you meet it doesn't always lead to a better/faster way of developing trust. IMO, any subbie worth their weight will take their time, otherwise, they may not be a sub but a bottom or a role player looking for a quick fix in a way. Nothing wrong with that and i'm certain if that is what a person is looking for they will be able to find it, in a heart beat.

Quality does normally come with patience and fortitude to not settle but to keep looking for the One that is their "beginning and end."
