Seeing as how LaBeouf is a 30-year-old adult by this point, being civil is typically the way to go.
Shia LaBeouf recently appeared on the SiriusXM Sway in the Morning radio show (via Entertainment Weekly) where he expressed his regret for what he said about Steven Spielberg.
Being in Spielberg movies probably opens quite a few doors for you, so LaBeouf gets that he maybe should have considered his words more wisely.
He admits that kinder words could have been used, even though his feelings about his experience were genuine.
