Text message break up

Hey tech-savvy friends: What's the etiquette for texting?

I'm constantly annoyed by friends who don't respond for a day or two, or sometimes never at all! Sometimes a friend will text me with a question, I will respond and then nothing! Ahhhhh... YOU TEXTED ME! YOU TEXTED ME!

Do I just let it go? Or should I get new friends? I'm always wondering if my phone is not working. But then I remember that three out of six friends respond back reguarly. So should I just be satisfied with a 50% texting success rate? Does that mean that 50% of my friends are rude? I mean let's face it, it is usually the same 50%.

My girlfriend says I'm crazy and I should just let it go, and I shoot her a "don't be patronizing" look and then she shows me her boobs to try to distract me, but of course it doesn't work because I can't let things go just like she said earlier! I mean, duh! And thus the vicious cycle continues. I can't get past the rudeness of it all—from people who apparently like talking to me! Or do they? I mean don't they? So if you can help me or have any answers to this thing that plages me daily, please let me know. Otherwise I guess I'll just continue the way I have been dealing with this my whole life—well, since texting came around—deep breathing and lots of booze.
