I've seen a lot of fics where Sherlock purposefully acts out to receive corrective attention from John, because negative-attention is better than no attention. I've also seen a lot of fics with Sherlock getting spanked as a punishment. And while I've enjoyed them immensely, I'm looking for something a little bit different this time...

Sherlock acts up/throws a tantrum, insults someone (intentionally or otherwise), etc., and he gets the silent treatment. Only a few days of this have him *begging* for John's forgiveness.
