The images that came out for this class involved before/after on a personal level
Before/After when you finally say something you have been wanting to say for so long, it has been waiting there for what feels like an eternity but the split second between when you haven't and when you have said it, everything becomes clear and things can never be the same again. Big changes, small sentences.
Before and after an event, when you have those mixed emotions but you're still both at the same time.
Before and after. You are you now, you were you before but those people are not the same. Your previous selves make up who you are now.
