There was a party and it was it bit formal. Walden was invited (including his family and the others).

The party was of course formal, kids were talking with each other while their parents chatting with one another, or whatever. Walden was leaning against the wall with his wife, Julie, standing next to him while their daughter, Ophelia, who was talking to her best friend, Alex. Alex dad (Wally) was talking to the other parents. (Disclaimer: Walden, Julie, and Ophelia never met Alex dad)
