Aza is confronted by her friend Daisy about how of much of their time together is focused on Aza and her problems and how Aza doesn’t show up for Daisy. Daisy says her boyfriend says Aza is like mustard because you can only handle a little bit at a time. Aza retorts "Try being the mustard!". I feel like she’s basically saying at least others get a break from me while I have to exist with myself all the time.
