When my family came to visit for my graduation, we took them to Boston for their last day here and we toured and walked all day and tried to go as many places as possible. We drove their rental car there and they left it at the rental car place, so Cal and I took the bus home. He promptly fell asleep on my shoulder and I thought I would snag a so-cute photo of us, except he caught me pretty quickly.
My advice to you? Somehow be sneakier. Tell me if you figure out how.
