Small thing, but the AE-1 light seals aren't craft foam, they're closed cell foam that won't soak up water or turn gummy over time. Craft foam is open cell and it'll break down and get sticky in a year or two. Buy a sheet of closed cell foam from a camera supply place or a craft store that sells it by the sheet, and cut your own strips.

Watching your phone turn into a psychic is both funny and creepy at the same time, like congrats, your pocket spy just beat your sister to her own announcement. But @michaeltorres nailed the part that actually bugs me, it is the stacking that gets you, not any one ad. A single baby ad could be random, but add up years of location pings, late night searches, shopping habits and suddenly the thing knows your life before your family does. Here is the boring truth though, it is probably not reading her body, it is reading the tiny clues we all drop without thinking, like a change in what she googled at 2am or how long she paused on some post. Still, "it is just math" stops being comforting when the math is better at guessing your secrets than your own sister. Nobody signed up to be predicted, we just clicked accept on stuff we never read and kept scrolling.
