AITA for making a very specific joke at exactly the right moment after my coworker told me I was not really part of the team
i joined a team at work about eight months ago. and theres one guy on the team, ill call him R, whos kinda made it subtly clear since i got there that he doesnt really consider me a core part of the group. not openly hostile or anything. just little stuff. not copying me on things. referring to the team in ways that exclude me. you know the type. that drip drip kinda thing that adds up over time
then like two weeks ago during a tense moment in a meeting he said something that landed harder than usual. basically implied that i wasnt really one of them and the team had its own way of doing things before i arrived
i didnt say anything in the moment. just let it go. figured he was frustrated and probably didnt mean it the way it came out. i actually really tried to be gracious about it
so fast forward to yesterday. were all in the break room. and R goes, dramatically, to the group at large, "i am exhausted, i need coffee desperately"
and without thinking i go "hi exhausted i need coffee desperately, im not really part of this team"
one of my colleagues laughed SO hard she had to physically leave the room
R went quiet
=
my manager was also there and she pulled me aside afterwards and said she appreciated that i hadnt escalated the original comment two weeks ago but that maybe i shouldnt have said what i said in front of the whole group
and i was kinda like. ok. but in my defense. it was funny. like objectively. the woman who laughed is still bringing it up
AITA?
