The fact that you didn't include the female (intentional or not) is great because it leaves so much to the imagination. We can all come up with our own story about who the other person might be and what they might be talking about.
We can only guess what the conversation was about, but if his T-shirt is a clue (a squirrel holding up two acorns and a caption saying Bigger Than Yours)...
Yes, there is someone there. She had a slight face painting. I must confess to not including her in the shot because there was too much distance between them on the bench.
The fact that we don't get to see who (or if there is actually anyone there!) he is having a conversation with makes this even funnier! Good choice not to include him or her.
