So recently moved to a new place. New roommates. Thought lets initiate a talk. Found out one of em is a web developer.
Me: So, what you working on?
Him: Web technologies
Me: oh great...I worked on ReactJS and AngularJS.
Him: Our company uses AngularJS.
Me: So you work on AngularJS, right?
Him: Oh no I don't work on AngularJS...I am a frontend developer...

(Awkward silence)
(Inner me: No shit. Need to find new place.)

Should I tell him?
