Random intrusive thought: Walkmen Without Hats
I've had headhunters trying to get a hold of me for the last fortnight for SRE work, and I'm really afraid that ship sailed a long time ago.
The voicemails are so incredibly desperate.

I can't tell you, after having moved to Georgia, how disappointed I was to learn that there was a town named Cumming and a county named Butts and that they were not coterminal.

I come at this from a "work through the mechanical parts for a couple hours a day" perspective, like playing rhythm and scale drills.
What I find perplexing is that Stewart was also an accomplished musician, but he writes his exercises strictly as if they're the recitals themselves.

I think the deepest conceit of Stewart's exercises is that they try to do too much all at the same time.
I've noticed that a striking number of them are keen to snarl you in algebraic manipulation or trig trickery hell, and I'm just over it.
Please, just let me exercise the calculus.

The boy used to chirp at me.
He chirps a lot at me otherwise! Just, like, not when he's keen on getting fed.

The guy busking with his saxophone on Murphy Ave has been endlessly playing Ed Sheeran's "Perfect" for the past hour.
If he keeps it up, I may decide to run home to fetch the bass and amp to play accompaniment for him. I happen to know the chord changes (don't ask).

Oops. Classmate who's doing peer review on my essay wasn't aware that I'm using a bibliography tool and wound up spending time reformatting my bibliography instead of merely redlining it.
I guess I need to find a way to reward the practice? This is awkward.

The infomercial is a lost art, and I am forever thankful that his catchphrase "Set it and forget it" is so deeply lodged in my brain that I have since forgotten (or become uncertain of) the kitchen appliance to which it refers.

Wherein I'm annoyed at Stewart again but for silly reasons.
I find that I need to pick trig integration back up, but his exercises suck, his exposition sucks worse, and the organization of the material within the wider corpus feels disjoint.
Just dedicate a chapter to trig, my man.
