Remember, this is a first date- do not scare your date away with a “too much too soon” impression. Nothing is ruder than talking on your cell phone during your date, or checking messages constantly while on a date.
While your fingers may feel attached to the keys on your i Phone try to avoid looking at the screen, turn off sounds to denote you have a incoming text.
If you must keep your phone on, then keep it short and express a little bit about the phone call if appropriate.
When the phone rings it breaks the flow of conversation, causes insecurity and keeps the other person wondering if you like them or not..
When you do a "silent treatment" tactic one must remember that the other person isn't psychic!
Sting talk is those things said usually in sarcasm to make a point or in anger to purposely hurt the other person.
