I’d generally agree with you as keeping in touch etiquette always gets to me, but I notice you said it happens after you’ve reached out. In my experience, if people don’t return a message etc, it might be for a practical reason (changed number, inactive email etc) or they might simply be preoccupied with something and miss it completely. As far as the CR, until we get upgraded to email alerts or a message after logging in, its possible (likely?) that said person simply missed a message post completely. If its any help, usually its not personal. 🙂
And I also noticed you were in hiding. Nice to see you around 🙂
