A homeowner's offhand remark about my cable runs made me rethink everything

I was finishing a job in a new build in Oakwood, and the owner, who used to be an electrician, just said, 'You guys always run the coax so tight, huh?' He wasn't being mean, just pointing out how I had pulled the line straight as an arrow across his attic joists. I told him it was neat and out of the way, but he said, 'Neat is fine, but houses move. That line's gonna sing when the wind blows or the heat kicks in.' I'd never really thought about thermal expansion and vibration like that. Now, for the past six months, I've been leaving a little service loop, maybe a foot of slack, near any entry point or long run. It takes two extra minutes and a couple more staples, but I haven't had a single call back for noise or a pulled connector since I started. Has anyone else had a simple tip like that completely shift how they do a basic part of the job?

Oakwood, that's a new build area with those big temperature swings. I'm just stuck on the fact he said the line would sing, like you could actually hear it in the walls. That's a wild detail I never would have imagined, but it makes total sense. It's crazy how a 30 second conversation can change your whole routine like that.

My buddy's old pipes used to groan like a ghost when the heat kicked on at night.
