I have friends from Akron as well as other places who many a times make these feel good statements to me.....i mean i make them at times too

They are something like

" Life is good"........"Its all about being happy"......"Sab theek hain re, Sab fit hain re"..........and so on and so forth.......

I wonder whats the thinking that goes into making such statements?

a) are they trying to make me feel the same way?

b) are they trying to convince themselves that these statements they make are true?

c) or do they really just feel that way?
