[@Rekaigan]

I would then apologize and then say I'll be more considerate in the future.

For example: Hey! Super sorry about reading but not really acting on your post Rekaigan. It was a good one, but I got caught up in a post and just kinda...forgot. ^^;
Supes-sorry and I hope it doesn't dissuade you from continued participation in 'The Faraway Land'.
>_<

Then I would probably try to throw a joke into the scene with an unrelated joke-y picture which could be seen as a bit of a half-assed attempt to lighten the mood.
Kinda like this, or something.
