1. Realizing that just because you’re an O’Brien doesn’t mean you deserve free drinks at the pub.
There’s probably at least several others with the same last name as you in O’Malley’s Pub, if the whole family isn’t there. They don’t expect free Guinness and neither should you.
2. Cringing at the idea of singing in public.
You’ll soon find yourself singing along to “Danny Boy” once someone starts it in the pub.
