"I see you invested some time into your nails, i bet you preffer phone calls over texting"
You see Sprks started a very good thread.
Almost each reply was a different answer, thats because people are different.
Its best during ur first day when u met the girl to ASK if she preffers calls or texting when she meets a new guy.Conversations are easy going once or prior the N-close so it will be easy for you to find out.
From my expirience younger girls (18-20) like sms game cos they just got off high school and thats a communication they used there for long time so they are used to it.
For older women (im 22 but i look older so i have no trouble to get women up to 29 years old) i used to get very bad results with texting, i acctualy barely could make some of them go out with me if i tried with texting althought we had terrific start.
Since i started phoning girls/women i always have better results.
Remember, its very easy to ask and find out, dont risk ur investment ($, time , talking) because u was too lazy to remember to ask.
In my opinion, if you havent asked - its best to go for a phone call, a self confident man would call - after all she doesnt knows u yet, writing text shows only that u know how to write, calling, talking shows that u r the same person she met yesterday, remind her how she felt with u and why she gave u the number and much more crap that women catch on by conversations.
