Once I had a project in school which was making simulated travel product with my group. I wanted to choose Europe, but other group had chosen it first. Thus, we couldn't pick it. The second choice I wanted was North America, but my friend preferred Africa. The reason I didn't want Africa was that it is hard to find lodgings and restaurants, and days of travel product we should make was too long for the type of travel which my friend wanted. The problem was solved smoothly. The other two members of my group thought my opinion was better. My friend did his best even though it wasn't his opinion, so we got a good result from it
