# Pairing session with Ben Holmen

> Let's pair program together! This is a low stakes and approachable hang - we'll take turns hacking on whatever we need to code that day. If we haven't met before, expect to chat and get to know each other first, then dive in. If we've met, we'll jump in and start coding right away!
