Most people in the world suck at communicating. Seriously. How many people do you know who always send thank you notes out soon after receiving a present? How many people always return phone calls and text messages promptly? The answer is...next to no one. And I know everyone has fabulous excuses, but shut up already. Just learn to be better at it. It's not hard. I swear. It'll take you only a couple extra minutes, and you might even gain a title like "Someone I can count on." That's not a bad deal.
On this same vein I must say that women are the worst when it comes to returning text messages or phone calls. And, I honestly don't care if they think they are trying to send a message by delaying their response or not responding at all. It's just rude. It's inconsiderate. It is much crueler in my mind for someone to shun or ignore you than to come straight to your face and bluntly say, "I'm not interested. Leave me alone." It would save everyone a lot of heart ache and wasted time if we just said what we meant, and stopped trying to be "overly polite" and therefore tactless. It is more tactful to be upfront and truthful. Beating around the bush and not calling people back is like being a middle schooler. Grow up ladies!
