hey James!
I hate guys who don't call when they say they will. I love it when a guy calls when he says he will call! Also, I agree with the above post which said say "I"ll call in a few days."That way you won't be forced to call a specific day, yet you can call in the "right time period" IMO.
I also don't like phone calls coming a week later. I love it when a guy calls the next day after a date,
if it went well, that is . if it didn't, I would prefer he not call the next day LOL! Basically, my advice to you would be to call ASAP (the next 3 days) if the date went well. BUt don't ever sound pushy on the phone. If you do, I don't care how well the date went, I would be thinking, "Desperate!"
HTH, sorry if my thoughts sound so mumble-jumbled, I've just had a very hectic week!
