Don't surprise your parents. If your relationship is serious enough to meet each other's parents then your parents should already know about the person you are with. Give your parents details about your girlfriend so that they know what to expect, and possibly how to prepare for such a visit.

Don't surprise your girlfriend. Most people are somewhat sensitive when it comes to their parents. Some parents are outgoing, some are laidback, and some are just plain weird. Your girlfriend should have some image of who your parents are.

Don't do it right away. Make sure that you have developed a fairly strong relationship with the person first. Meeting each other's parents can be a big step in a relationship, and is often a sign that the relationship is getting serious.

Just be yourself. While it is important to try to impress your girlfriend's parents with good manners and appropriate behavior, it is not a good idea to act out of character. You should just be yourself. Your girlfriend likes you for you, it is important that her parents like you for similar reasons.
