I would just like to add...
This is a way to meet the real person.Then if we judge we can be more justified in our attitudes.
If he has been around 40 years.Then lets hear his opinions on how it was back then to now.
What mistakes or regerts he did,he wish he could take back.
Or any other matter.I have been a cleaner a very long time.
An all I know is when,I fail to learn even the slighest thing to improve myself.From anyone.Well get my coffin ready.
My 2 cents...
