I can be open about my T1 mostly. Other times I can test & inject privately either in the back of my privacy glassed van or shielded by a work's truck door?
I'm pretty stealthy with it regarding certain company I don't know..
I dated someone once who during my openness with my condition seemed to take an unhealthy dark interest with the bloodletting & inpalement? (Start the car..)
Years ago, I was spotted in (in what I thought was an empty) a changing room at college injecting (classic syringes back then.) by another student. The rumour went round I was a "druggie."
I was testing in a staff room & a driver came in to make tea. "AIDS test?" He commented. Yeah, but don't worry, your not my type..
I was diagnosed in an era of pee testing? I felt the meter was civilised, but occasionally the act offends the observer.
Even with a simple comment of, "oh, I couldn't be doing that.."
