So-called friends need etiquette lessons

I'm to assume that when someone considers themselves a friend to you, that means they will be exactly that, a friend. That means, they call you, or email you, or come visit you when they have time. It's been well over a year since I got married and they were IN my wedding and over three months since I moved from my hometown... there are people who are on Yahoo IM and they see me as available, but do they even say, "Hey! How's it going?" Nope! They sit there like a total stranger. This has been going on for as long as I can remember. There's MySpace.com too... they don't get in touch through that either! Do me a favor people... don't say you're my friend and then drop from the face of the earth - not to mention talk smack behind my back. A pox on your other friendships! I bet mildew on the walls from humidity make better friends than you!
