It’s sunny today. After a wild night’s drinking spree, my dad slept like a log until noon. I believe I failed in my responsibility to ensure they got home safely last night. At that festival, Dad became heavily drunk, (which was) evident from his incoherent mumbling. The alarming moment came when Dad, unsteady on his feet, nearly tumbled off (down is more likely, or tumbled off the end of) the escalator when leaving. Thankfully, Mom was behind him and was able to brace him with all her strength. Had I been in her place, he would have likely knocked me down, and all the people standing behind us. (If he is falling forward how does he affect the people behind him?) This incident has made it clear that Dad should never attend another beer festival ever again.
