Answer:
One time I was riding a bus with my family, traveling around a resort we were staying at. We had been promised that day that we would go skiing, which was a big delight - the resort was well known for its amazing slopes. Soon after we entered our room to prepare for the long day ahead of us, my sibling insisted that he wanted to go swimming - something of which he could do anytime he wanted. After refusing to leave the room until we agreed, we had to take off our gear and go to the pool. I was frustrated and disappointed, but I didn't lash out. Instead, I sat with my mom in one of the hot tubs while my brother swam in and out of the building.
My brother changes our plans quite often, and sometimes it's hard to deal with him. Sometimes it's better not to cause an argument, however, sometimes it's not always healthy to keep your feelings stuffed inside. If we don't get angry sometimes, then our feelings simply swell up inside of us, and we turn into a ticking bomb. It's okay to be upset sometimes, as long as it's within reason. Humans are one of the only animals with such a range of emotions - so why hide them?
