You're friend who you talk to all day on Sundays, and no one else. they are irreplacable. the only time you can have a different sunday buddy is when they are not home or if they die. And there are rules to Sunday Buddies:

1: You have to know them

2: You have to get along with them

3: It has to be someone no one would think of.

4: Has to be able to talk about something all the time (no awkward moments)

5: has to have a brain that works the same way as you, but uses it differently
