When in doubt, turn to a trusted friend for sound advice:

Grasshopper:  You’ve never steered me wrong when it comes to my choice of drink or drink habits.Tell me this: Is it wrong to open a bottle of wine if I’m alone in the house and it’s certain I’ll be drinking alone?

Master:  Nope. Sounds like an opportunity to enjoy a bottle without the fear of an argument or sexual favors in the end.

Truer words are rarely spoken.
