Ever since the TSA implemented its liquid restrictions on carry-on luggage, I've found myself paying special attention to the liter size of certain toiletries. Just this morning, I realized I intentially turned a bottle of my shampoo around just to read the liter size. Then as I was brushing my teeth, my eyes darted to the bottle of sunscreen bottle, the jar of lotion, the tube of lipstick. I feel like I'm training myself to eyeball what 3 ounces liquid -- or what the TSA categorizes under "liquids" -- looks like. Maybe it's just me.
