In this case, I’d suggest the application is that this client did not wake up that day thinking “who’s time can I waste today” but, whether through poor composition of the message, simplemindedness, angst, fear, uncertainty, inexperience, etc -that was the result.
As @SecretProvider implies, I hear from other guys that in the first two texts, they can tell whether someone is serious or not. I believe that to be completely true. In this case, it did not develop into endless texts or requests for pics etc…but those are the ones easy to spot!
The challenge is responding in a manner that meets them where they are - uninformed, scared, inexperienced, etc - and gets them talking…then they probably have a client for life IF the provider has the time/tolerance to develop the lead.
