I'm not as bad as Morrice up there but did I ask you to text me? Did I ask you to call me? Did you ever stop and think that maybe your "first contact" wasn't appreciated?
So, you ask a chick for her number, you call her, she screens, and doesn't return your call. BFD get over it. Why did she give you her number to begin with? Probably because if she didn't, you'd call her a bitch, and if she gave you a wrong number, she's a *unt.
It's not the best way to handle things but of all the trials and tribulations we face in today's society, a non-returned phone call, email or text shouldn't be giving you that much grief.
I for one am guilty of not returning calls not because I'm rude, but because being self employed I'm pretty much freaking busy all the time and when I DO get some free time, I just like to veg. I also realize that others are quite busy and if they don't respond right away? I'll try again in a few days. I go by the 3 strikes rule: if I iniate contact 3 times and you don't respond, you're not interested and I delete your name/email/number from my files.
