Knowledge: To start drinking coffee, it is best to start with one shot of espresso due to high level of caffine for a starter. On the other hand, cocktail can be enjoyed by everyone as it does not have strong taste of alcohol, which is a great drink for beginners.

Conversation:
I have never drank alcohol.
That would mean you are in a condition of sobriety, which is not having any noticeable affects from alcohol.
Yup, but I want to start now. Which drink do you recommend for a starter?

Response: Oh sure. For beginners, cocktail is a great drink and can be enjoyed as it does not have strong taste of alcohol.
