Checking your mobile phone during a date is one of the quickest ways to make someone feel uncomfortable. Whether you're taking a call or a text, using your phone sends the signal that you're not interested in your date. Even if you want to text your best friend about how great the date is, don't do it. Instead, concentrate on making your date feel special. Even if there are no sparks, be courteous, pay attention to the conversation and offer a goodnight handshake.
