I hate telephones. I'm awful on the phone, avoid calls, don't call back. I just... it's uncontrolled conversation. I like to have conversations in person where you get facial expressions, gestures, more context. On the phone you can be caught off guard. If that's the case, better make this call short and have only the important information. "We're meeting when?" "What am I bringing?" "See you there." The end. But why not just use text/email for such informational conversation? "Reply at your own pace, but please do so soon."
