I: Hey I've got this medicine unit treat today, can you cover for an hour or so?
I: Hey, I can hardly breath, severe asthma...and to make it worse sinusitis has struck me like never before. I'll take my only permitted leave today.
She: I've got this unit treat today. Can you cover the duty for me?
I (finding it hard to breath): Fine *nothing to say*
She: Now that I took your duty yesterday, you'll take mine today right?
I (poor health, wheezing): Okay
I: I can hardly breath. Need my inhalers. I think I'll cover your pending duty some other day?
She: Yeah okay
After fifteen minutes
I reach home. Phone rings
She: I need to go home. Can't take up duty today
I (frustrated, angry, desperate): FINE
Day 5 (Sunday)
I: Got some works today. Could we exchange duties today?
She: No. I plan to leave as soon as possible.
Gets an sms: Won't be coming today. Fever, headache, vomiting
