I've traveled around the country and I read local newspapers and all of that and it's a sad sad thing to go from city to city and see the small newspapers and they're tiny. They're tiny not only in size but also in scope.
I'd say that after my father passed my writing changed it went deeper. Most would say 'matured' but I don't think I'd use that word in relation to my progress. I think 'change' is a little more accurate.
