I advise shying away from these guys. Everyone should date at their own comfortable pace. Detox, de-stress, distract, discover, and repeat. Maybe he was a spy or something. This person may be too into themselves or really has a problem with their ego or self-esteem.
However, this can also vary. You hear those trumpets? Have they been bragging about their job and how much they make, or have they been pretty funny and outgoing?
