My sister is beginning to get on my nerves. We’re twins so we’re close and get along for the most part. But she’s had a number of health issues over the past couple of years that have made things challenging. Because of this most of us have adjusted things around her schedule to be considerate. But she’s started to behave in a manner that is selfish and astounding to me. She will do the most to get out of any sort of work, but will be fine as soon as it’s done. Whenever we have company she’s done her absolute best to make herself the certain of attention. She is quick to talk over people and interrupt and then behaves poorly when she is called out on it. Whenever we both have to get up to something together I try to be as professional as possible. But she always has to act out or try to be funny and then I look bad by default. If you try and get her to tone down her behavior she’ll immediately sulk and act difficult which makes us look worse. I’m becoming more and more inclined to leave her out of things because whenever she’s involved it HAS to be all about her.
