Back when I was still with Liam I got a bartender's certification kit to perhaps go into that career. I studied the whole book and learned a lot about the proper etiquette surrounding alcohol preparation and ingestion, but I never actually took the test.
I dunno why, maybe I just didn't really want to become a bartender, maybe I was too freaked out over the concept of taking a test voluntarily, maybe I was just lazy. I know Liam was pretty disappointed at the time, but I think he just wanted to live vicariously through my fancy new occupation.
And he might have paid for the certification kit. Whatever, at least now I'm drinking my troubles away properly.
