person A: I never thought I would be where I am today. If you would have told me I would go back to school at 27_comma_ I would have thought you were crazy.
person B: why did you go back?
person A: I had always wanted to be an electrical engineer_comma_ but had settled for life in the service industry (not knocking it). I re-taught myself basic algebra_comma_ and was accepted to a state university two years ago! 
person B: good for you_comma_ best of luck!!
