I've got lots of secret girly reminders surrounding me on a daily basis. For example, heaven help me if a stranger picks up my cell phone. I currently have this cute gif as the wallpaper reminding myself to stop and smell the coffee. Doing so en femme is even nicer.
My computer at home is equipped with a couple of desktops. One features girly and transgender themes, the other is boring guy colors and designs. My favorite Ranma 1/2 gif of Ranma being doused with cold water would probably invoke too many questions when the parson comes for a visit. However, Windows "dessert" color theme screams generic guy computer.
Mom always told me to make certain to wear clean underwear in case you are involved in a traffic accident. I'm not certain which would raise more questions -- being in an accident while wearing 2 day old underwear, or wearing satin pink heart panties trimmed in lace. Either way, I prefer the second.
Sometimes my girlish ways are discovered. I once had to visit a doctor and absent mindedly shaved my legs the night before. The problem was an ingrown toenail. I realized what I had done when the doctor asked me to remove my shoe and sock. He examined my foot, noticed the lack of hair, and raised my pant leg. Do you shave your legs? he asked. I tried to act as confident as possible. Of course I do. Is there anything wrong? The doctor assured me nothing was wrong and wrote a prescription. Thank heavens I didn't need an injection in the rear. I probably would have passed out and the doctor would have used my cell phone to call a friend to come get me. See gif above....
Still, in all the years I've been doing this, I have yet to really been called out. Keep it girly, friends. It's better than any alternative out there.
