I Am An Introvert

My brother left a message inviting me to a public event. It's been days and I still haven't returned the call. My mind tells me to call back, but my body doesn't want to. I don't like phone calls. I feel like my peace is interrupted and I start to feel nervous or irritated. Calling people feels like wasted time, but I don't have my brother's e-mail. The only way of contacting is calling him on the phone. Ugh!
