Never go out with a person you really do not know and never let him pick you up take your own vehicle and bring a friend , if that person feels upset about you bringing a friend most time he got something up his sleeves , and if it is your first date don't use a clothing that will turn on your date , male or female have a weak mind . have a conversation on sports or politics  that way you can find out how intelligent the individual can be don't disagree with the person comments the person may get offended just compromise with the person .
