Fun vs. Grief.

If you go out against the will of the other you are going to get grief. It is going to take a damn good session to counter-act the amount of grief you cop, but if the session is a good one, it can more than counter-act any amount of grief!
If you go out with full blessings and have an awesome session then you have maxed out the graph and life does not get better.
If you go out with blessings and have a crappy session then the fun vs. grief is still a good ratio and the session is a success (better to have a **** session than none).
If, however, you go out not-so-blessed, which will end with endless amounts of grief, and the session is not such a good one then the fun/grief ratio is all out of whack and it will amount to a crap session and endless grief when at home = not good at all!
I always try to aim to keep the fun/grief ratio at least 1:1 or better eg. if it's blowing its tits off and going to be a killer session then bugger it, everything else comes in second and the grief will be worth it. If it is looking like being average conditions then I may pass up a session or have a short session to keep the other happy.
