Since the virus, L and I tell each other that we love the other at the end of session. Here almost word for word how it goes:

L: (5 mins before times up) I know it's about time, is there anything else you would like to talk about?
S: Are we okay? Are you mad at me?
L: Yes we are okay. No. I'm not mad at you.
S: Ok
L: Ok. Are you ready to say goodbye?
S: Yes
L: You first or me first
S: (I randomly choose)
L: S. I love you.
S: I love you, L.
L: See you soon.
S: Okay. Thank you.
L: You're welcome. Bye bye. (Sometimes we wave).
L is the one to end the call.
