I have a friend who I generally like but she does one thing that I find irritating. We generally make a restaurant reservation in one of our names when we meet up. She routinely arrives 15-20 minutes in advance of the reservation and immediately texts me, "I'm here." What am I supposed to do with that info? I am usually in transit and it just makes me feel stressed out, even though she is early and I am not late. What is the purpose of sending such a text? And there is no way I can ask her not to, right?
