voicemails are tricky but i have found a couple of rules i like to use
Donts:
#1 never state your name, she should know who you are and have your number already in her phone
#2 never ask her out on a voice mail or text message
#3 never say something like, just calling to see what you're doing. that can be interperated as, i'm bored, with nothing to do cause i have no life, and you are my last resort, and no other options.
#4 never give her the assumption that it is necessary that she calls you back. it makes you sound needy and desperate. dont say call me back when you get a chance.
Do's
#1 Keep all messages short and to the point.
#2 tell her something exciting you are doing right now, you thought she should know. this one includes texting.
#3 tell her you will call her later or talk to you later, instead of she must call you back.
#4 instead of stating your name say, its me.
these tips are to maintain you as high value. i also like to use baiting techniques to get her to call me or text me back. one of my fav lines is this, can be used as a voicemail or a text.
text: "omg the craziest thing just happened!" on vm, just add, hey its me & i call you later to tell you all about it.
my 2nd fav is "omg i just saw your twin!"
by the way just have a couple of made up cool stories to tell when she does actually call back, insert DHV's.
