When getting to know a 'new to you, it oftentimes pays to

new-to-me acted flawlessly, so I wasn't going

HERE you will see what a mistake that
mindset was. Clean And if stiff, go ahead & oil
now, so that it won't decide to deny you
access IF you really need to get in there.
I could go on & on, but this is all common sense. Once you've really looked
for trouble and got it all sorted out, you'll get much more
relaxed when behind.
