Input: This happened a couple of years ago, and I still occassionally think about it.

In high school, I had a friend who I walked home with from the bus stop every day after school, since we were neighbors. I'd known her since I'd moved to that small neighborhood some ten years prior; we were never really close friends, but rather more close acquaintances, as we were the only two people roughly in our same age group living there. Nothing more than a three-four minute chat about the school day, the weather, or, occasionally, gushing about some new album that'd come out recently.

One particular Friday afternoon, the neighborhood was filled with noise. About two or three houses that day were getting work done on various parts of their house, their front lawn, or their backyard. We were chatting it up and laughing about something my Spanish teacher, whom we had a mutual dislike for, had done that day. Passing by a small group of the people working on the front lawn, I waved and said 'Hola!' They waved back with smiles.

About seven seconds later when we'd passed them, my friend stopped and heavily scolded me. In fact, I think she was about to blow a fuse; I'd never seen her angry in my entire life, let alone this angry. She yelled that it was extremely offensive and racist to speak to them 'in that way,' saying 'They speak English, ya know! That was so insensitive!'

I was dumbfounded. Startled and frightened, I just mumbled 'yeah, sorry, sorry' till I finished walking home. In the shower later that day, I was still thinking about what I'd done wrong -- how could saying 'Hola' to *Spanish* people be offensive? In context, I felt like an asshole. But if one of the workers walked up to me or her and said 'Hi,' in English, would I have the right to be offended?

Was I being culturally insensitive or something? Since it was a Friday and the weekend passed before Monday, I couldn't tell if she either forgot or if she had put it past us. AITA?
