what’s a red flag on a first date?

A red flag on a first date is a warning sign or a sign of potential problems in a relationship. Red flags can take many forms, but some common ones include a lack of respect or consideration for the other person, dishonesty or deception, aggression or anger, controlling or manipulative behavior, and excessive drinking or drug use. These behaviors can be indications that the person is not suitable for a healthy and fulfilling relationship, and should be taken into consideration when deciding whether to continue seeing that person.
