Any time.  

I am what is known in the educational systems of the US as a "quick study."   I'm equally right and left brained, so I've done well in medical graduate work, law school, flight and ground school ... used to be a California State Math Scholar, can sew, cook, build a computer, do network punchdowns ... whatever.  If it can be properly explained to me, then (physical limitations considered), I can do it.

Makes me a real know it all much of the time.  But, my friends appreciate me anyway.

Could be worse, could be raining.
