I'm merely responding to posts on a forum. Which in itself is hardly a strenuous or in-depth affair. If someone were to call me, right now, I would answer the phone with similar nonchalance.
Even if one were to assume that such was not the case, would it not also imply that you are more overly invested in this discussion than you claim? Or is this but another case of 'rules for thee but not for me' at play?
