integrity-Do What you say you will do (Mr.Lincoln)

what i saw in this video was a promise that Lincoln made to his mother before she died. i guess she was dying from smoking tobacco and drinking whiskey. although he wanted to but he had a promise and the person that he was walking with had offered him whiskey but he said not thank you, he then told him that if Lincoln didn't take the whiskey to at least smoke with him. then he told him a story.

" Lincoln promise me that as long as you live you will never smoke tobacco and drink whiskey"
Mr.Lincoln up the the day he died he never drank or smoke to keep his mother promise.
that was an act of integrity. you don't always do what you say but Mr.Lincoln did.
