where do you draw the line of when it's appropriate to hold a conversation with someone who's currently using the bathroom?
never ever ever ever ever ever ever under no circumstances wtf no
text messages/other text-based conversation is fine
phone calls are fine but no face to face conversation
talking through a closed, locked bathroom door is fine
only if you're both on the shitter, either in a public bathroom or on the phone
bathroom door may be open but the other person won't look that way
I will sit there in the bathroom with you making solid eye contact like a dog
option of infinite nuance
op wtf you forgot the most obvious answer
[measure this by the closest people you know - family, spouse, siblings, etc. not like strangers or co-workers.]
