Can I Borrow the Khakis?

I just came across a key that was given us on the day we bought that house 14 years ago. My son identified it as the one he kept, based on the key ring it was attached to and has added it to his current one, It was a happier time for him, before he went to live with his dad and then his grandfather.
He has become a fine young man through it all. It is what we wish for our children: to grow up and be their own adults.
You can have the key to success and then, the key to the city.
You can hold the key to someone's heart.
You can sing songs in the Key of Life, according to Stevie Wonder.
Our DNA holds the keys to our lives (and this story tells of how getting rid of some can prolong life!)
You can be entrusted with a house key at a fairly young age and when you reach one of life's milestones, you ask your parents for the keys, to borrow the car that they taught you to drive. (I taught my son to drive, and that was quite an experience, considering he worked for a company that repaired vintage race cars. My daughter taught herself to drive and boy, was I surprised to find out she did!)
Which in a very round-about kind of way brings me to:

Khakis

If you live in Boston, like I did for twenty years, if you ask for the kah kees, you may or may not get the keys to the "cah," you may just get a pair of pants! Notice the subtle differences in pronunciation.(I still do not know what they do with all those extra "R's" they don't use!)
Additionally, khakis are a specific fabric, fit and color. They are NOT black, brown or green. They ONLY have FOUR pockets. They can be pleated and cuffed but never riveted.
Think school uniforms, that's what khakis are. But kah kees will not get you into my car like this will:

I love my car, I love to drive it and it has loved me for 160 of its 213 thousand miles. We have taken it places that Lexus just THINKS it can go. I hope to get 350 out of it and when I do I'll get another one just like it (just with fewer miles). Meanwhile, I'm going to hang up my car keys so i'm not digging through my khakis later to try and find them.
