My friend Grace invited me to a board game bar to play and have drinks with her, her boyfriend, and one of their friends, Nick. We went to get drinks in pairs, Grace going with her boyfriend, meanwhile Nick and I stay at the table and vice versa. So Nick and I had plenty of times to talk, just the two of us. Nick started the night by telling about his recent career change. He decided to quit his previous job, go to a Kuri boot camp, and he got a job as a developer one or two months ago. He was very proud of himself and his new salary and he told me this multiple times. He never asked what I do for work, but talked about his new job quite a lot, occasionally saying, Sorry, you don't understand that. Haha. During the entire evening, I never told him I have been working as a software engineer for the past four years, because he never asked and honestly, I found it a bit entertaining. When it came to drinks, he invited me to every single one. Don't worry about it. It's not a problem with my developer salary. I told him multiple times he doesn't have to pay for me, but he insisted. At the end of the night, we were saying our goodbyes. He took out his phone to send me a friend request on Facebook. My job is listed in my profile, so that was when he realized that I'm a software engineer. He asked me if it's true that I'm a software engineer and I answered yes. He asked me why I haven't told him, why did I let him believe I was a cashier like Grace used to be, and why did I let him pay for everything when I probably earned more than him? I told him that he never once asked and it was his fault, he assumed. He could have simply asked me about my job, but he only wanted to brag about his. But if he wants me to, I can pay him back for the drinks. He was angry and said I made a fool out of him. I think he did that, not me. But now Grace and her boyfriend are on his side too, saying that it would have cost me nothing to tell him early in the evening and I only kept for myself for my own entertainment. Well, I did find it entertaining, but I don't really feel like I did anything wrong. Am I the asshole?
