Intro
It’s a normal morning. You get dressed on autopilot — same routine, same mirror, same bra you’ve worn a hundred times. The only weird thing is that it takes you a second longer to fasten it. Not because it doesn’t fit. Just because it feels… a little tighter than you remember. You shrug it off and keep going.
What kind of day are you heading into: school, work, or staying home?
