fun post, jillie! here are a few that i can think of:

-breathe or take a deep breath
-why do you ask? (if i ask her something personal)
-tell me what the tears are for
-i'm proud of you
-says your mom (after i say something that comes from my childhood)
-and what do you make of that? or what do you think that means?
-that's not your energy, give it back to that person
-you're doing great work
-i'm not going to abandon you, that's just not part of our relationship (or some iteration of that)
