I love when my teenagers are like "mom, you know you're ADDICTED to coffee, right? Like, you're aware of that?" because I drink a single cup every day. Little puritans these youths

By this logic I am also addicted to showering and brushing my teeth so many we could learn a thing or two from mom's example idk

Probably not, since those don't contain an addictive substance (and are also very, very boring). But I also don't think 1 cup a day creates much of an addiction. I can tell I had a chemical caffeine addiction when I had 2-3 cups a day, but the 1 doesn't do much.
