Original Commentary
And we explain who this woman is. I would've added it to the previous comic, except they both ran on the same day. Anyhow, she has explained time zones to Caleb several times and he just doesn't understand the concept. It probably took a lot of patience to explain phones to him - Terrence

Modern Commentary
Caleb does not have email. He doesn't have a cellphone or social media. His manager, Michelle, works hard to keep it that way. - Terrence
