Went by an ex-girlfriends place the other day... she'd talked me into keeping an eye on her place while out of town.
While there, I noticed her front door hinges were COMPLETELY dry, to the point of it being hard to move the door. The frame flexed, and you could hear it up the block. Huge heavy door, sporting 3 big beefy hinges.
Being the nice guy I am, I offered lube it.
I did it the day she came back, and did it right too... took the door down, cleaned out a couple of tablespoons of dry rust spooge, and put it all back together with a thin coat of white lithium grease.
What a difference! Once done the door would 'float' all the way from one end of it's travel to the other with only the slightest nudge. She was tickled pink at the time.
Now I'm catching hell about how anyone could 'just sneak in unannounced', and how she can't sleep anymore because of it... wants it put back like it was, and won't even discuss getting bells or some other noise maker.
Making matters worse, I went through this same scenario several years ago with someone else, and had even told her the story before I lubed the door. She'd thought it funny at the time.
Wish ol' Sam Kinnison were still around. Sure miss him sometimes.
You just can't win. Hope she doesn't up and sue my ass. She's the type that'd take a crack at it... and has successfully done it (to others) for less than this in the past.
