- They laugh. A lot.
- They never shush anyone. In fact, sometimes they’re the ones who need to be shushed (Okay, that could just be me.)
- Okay, this is not so surprising, but they usually carry books or tablets with books downloaded so that they can read at any time.
- Their conversation can shift from databases to rampaging elephants to Snow Patrol songs over one glass of wine.
- They have a wicked sense of humor and can hold their own with any other group at a restaurant. With the possible exception of Irish rugby teams.
