SHORT ARTICLE
My brother is crazy about playing video games, but I’m more interested in travelling and meeting people. I really enjoy visiting pleasant places and trying new food. Last year, we stayed in a beautiful town where everyone was very kind and welcoming. However, not every experience was positive. One hotel had unpleasant service, and the staff were quite unkind. My brother and I sometimes disagree about what to do on holiday, but we usually find a solution. I’m tired of staying at home all the time because I like discovering new places and experiences.
