My grandma always said talking helps your hands focus, which makes sense with what @thea452 said about chatty clients. I definitely zone out on the quiet ones sometimes when someone else is telling a full story.

Saying it's an exaggeration shows you haven't had to fix a hand-drawn error on site. I've been there, and one small mistake in a sketch meant hours of rework. That's why I always double-check measurements with a physical tape, even with CAD models. Digital plans can lie about clearances, so you need to check in the real world. The quiet focus of drawing by hand is nice, but catching errors early saves so much trouble. Why risk a field fix when you can check it twice?
