Only one event really sticks out to me. I was around 10 (and I still believe I was old enough to have "known better" because I wasn't entirely unfamiliar with the concept of sarcarsm) and staying at my sister's house because during this particular year I was being homeschooled. While my sister was at work, my nephew (4?), my niece (3?), and I were babysat by my sister's mother-in-law, an Indian woman with a strong accent. I always had difficulties with "Oma" because she was hard to understand and she seemed to be angry at me or the kids for reasons I couldn't identify...
Anyway, one day the three of us were in the back bedroom, and for one reason or another we had decided we didn't like Oma, and either all three of us or just the two younger ones were jumping up and down singing, "We hate Oma!" Oma heard, got upset, and eventually ended up saying something like, "Why don't you just lock me out of the house then?"
She followed this by walking out the front door. I took this very literally and went ahead and locked the front door. Then (and for some reason this was the more shocking part to Oma) I ran around to lock the back door as well. For the next little while, I felt very proud of myself, and I proceeded to "prove" that I didn't need her by feeding the birds and fish. That's all I remember of the event... But it led to a huge fallout, and my brother-in-law never forgave my mom for having raised me so badly that I would behave this way toward his mom. There was a huge rift in our family, and we weren't allowed to see the kids for several years afterward.
