The purpose of a first date is to determine if there is any kind of chemistry between two people to warrant a second. If you manage to be boring, then there is a good chance that you'll be having breakfast for one in the near future. Although dating in Las Vegas can be shrouded within the entertainment of the city, your date can still be bored with you personally. However, there are some signs you can watch for that will alert you when things are starting to go awry.
The questions a person asks can be a telltale sign of their own interest. If they are just trying to be nice, these questions may be simple and feel more rhetorical than that of actual intrigue. A date that is interested in what you have to say will ask questions that delve deeper into the conversation. They'll ask about specifics and details. They'll work harder to understand your story and will seek clarification regarding certain aspects. In other words, it won't feel like your simply filling out a questionnaire as an organ donor.
Body language can tell a lot about a person and his or her response to the situation. A person that is sitting forward toward you is showing signs of being interested. If he or she is sitting back in the chair away from you, it's a bad sign that you're not going on a second date. Folding the arms is a defensive sign and is often perceived as protecting oneself from the situation.
Eye contact is one of the most promising of signs that someone is interested in you or not. Someone that can keep regular eye contact during a conversation may be intent on knowing more about you. If his or her eyes are wandering around the room or checking out other people, you may have lost the date's attention. Someone that is in to what you have to say will be looking at you most of the time.
