Invest some effort into flirting, but don't expect a lot of return initially until you "click" with the right person. Search the identity online, to see what else you can find out. Online flirting is a marathon, not a sprint.
If, for some reason you do not like someone or that person did not satisfy your expectations please say so openly, but respectfully and politely. Wait until you're in person to talk about these things. All in a fun and safe way. Mystery is one of the greatest forms of seduction — it leaves your date thinking about you after your conversation, craving more. Looking for a soul mate is easy and fun with our application. On the other hand, don't give up too easily.
