What is he invited me to a party with his friends?

As an AI language model, I do not have access to personal or specific information about individuals or their social events. However, in general, being invited to a party with someone's friends typically indicates that the person values your friendship and would like to share their social circle with you. It may also suggest that they feel comfortable around you and enjoy spending time with you. Parties with friends can be a great opportunity to meet new people, make connections, and have fun together.
