This is what countdown widgets are for on your phone, from the moment you last saw her you should wait 27 hrs 14 minutes and 54 seconds before calling her again, a second too early and you are too keen, a second too late and you don't care.
Them's the rules I'm afraid.
Agreed, don't play games and start as you mean to go on. If she likes you she won't mind if you text her right away. If she doesn't, it won't matter when you text herDon't mess about. If you like her then text her.
This generation's obsession with texting perplexes me. In my day if you met a girl you liked you got your bird out and gauged her reaction. Honestly, kids today.
Too late she's probably already woken up with someone else
