If we ever had any type of relationship and you are feeling the urge to contact me via phone, here are the rules:
1. I don't want to chat with you about my love life. Ask me out on a date.
2. I don't want to hear about your recent breakup. Apologize for your past behavior.
3. I don't want to talk about work. Apologize.
4. Be upfront and honest and tell me why you are contacting me, rather than a confusing, "What's up?" Chances are I'll meet you in person. Otherwise, I wouldn't have picked up the phone in the first place.
