quantifying a call-day

1 call day
= 9am on day 1 to 6pm on day 2
= 33 consecutive working hours
= time taken for mum to go to work and off work, then back home, pack things & have dinner, then go to the airport, flight to london, followed by another flight to rome, taxi to hotel, and check-in & settle in hotel

i left home together with mum on friday morning, and both of us went to work, yet she has done so many many things before i'm off duty, on a call-day... kinda depressing...
