what for instance

Security men,accountants,cooks,maids and sundry others.There seems to be a common DNA to all of these.Why for instance does a security guard watch with great interest while you struggle to squeeze your car into the only available space,only to pop up and tell you that you cant park in that place.Didn't he see you struggle with all that wrestling with the wheel or was it some pleasure he got out of it.
Why for instance do maids insist on bunking work on Sunday when that's the one day you want to do nothing.I have stoped looking forward to weekends.The maid will not turn up the washing will pile up and when its time for a hot cup of tea the cook would have also done the bunk so there you are ,cooking and cleaning till the cows come home.Isn't it perfect how guests also decide to turn up just then.
Why for instance does the plumber,carpenter and electrician swear to come at ten in the morning and then turn up when they feel like it ,if at all.Why for instance do we have to bunk work and wait patiently for these people when they have scant regard for your time.
Why for instance does the water tanker and the state transport bus believe they own the road,and that the small guy on the bike or car is meant to be run down.
Why for instance do courier boys always ask for identity when they deliver mail addressed to you at your home.They also ask for your relationship to other members of the household.I have taken to claiming to be the housekeeper and considering most of the boys haven't a clue if this means wife,mistress or general dogsbody,the conversation ends right there.
Why for instance am I agonising over all this when I know for sure that if all of them behaved differently I may feel lost and out of place in this world.I just wonder
