Month-end thought

Capping the month of March with this thought: Why expect an excellent result when you know one’s limitations.
I had a breathing test for an hour today. I am connected to a machine, stuffed with a mouthpiece, and my nose clipped while I sat inside a closed cubicle.
I have to breathe through my mouth only; breath in, breath out, and blow. We did these several times depending on the speed and the length. Aside from feeling tired, I was perspiring because my claustrophobia seemed to have catch up on me.
The attendant gave me then three puffs of Ventolin. She asked me to rest for 10 minutes. We redo some of the procedures.
After going through the same routines, the attendant finally told me, you could have done better. My mind shouted: WHAT?
Trembling and feeling dizzy, I told the attendant, “Thank you and sorry. That was the most I can do.” I left and looked for a corner where I can regain my strength and compose myself.
