If there's time to clean the flat, find an inspirational quote and post a cryptic message hinting something's amiss, there's time to explain briefly what's wrong. If the issue is so personal, sensitive and emotive that he doesn't want to divulge details, then it was completely inappropriate for him to post in the first place.
Cue Melvin leaving his lovelies to "unindate" him with messages of deep concern and his next story to lead with "Hello my lovelies, I'm fine, I'm absolutely fine"
This has particularly bugged the bejesus out of me tonight as its so insidiously emotionally manipulative at a time when many (myself included) are perhaps reflecting on loved ones lost and sadly missed.
Bawbag.
