Look, that's not totally true. State boards update test requirements, they just also make you learn the basics first. You need to understand color theory and damage from bleach before you jump into vivids or color correction.

Wonder if it changes how a house sounds inside... like, does it block noise better or worse than the pink stuff? Fire safety ratings would make me nervous with all that cotton.

Diving deep with the meter first usually finds the problem quicker. Simple checks can just waste time on fake leads.

Ugh the midnight snacker. Had that happen in Barcelona. Our group fund was for pasta and sauce. Woke up to empty boxes and a single dirty bowl in the sink. Person never fessed up. We started just buying our own small stuff after that. Locked cabinet for shared things if the hostel has one.
