I didn't see your reply before it was edited .... but what I am referring to by "lightening up" is that the world won't stop if a member doesn't come back to a thread and post right away.
It's probably just a case of "forgetting".
So, good gracious, no need to make a gloomy issue out of it !!
In any case, no one is "obliged" to post. You yourself have chosen not to post in a particular thread because you consider it to be weird or common but others who think quite the opposite won't condemn you for it.
