Going by a primary school today, I saw an elderly man standing right by the fence, talking to the kids, looking a bit confused. Getting closer, I saw a four-year-old girl talking to him, saying, over and over, "Kiss me! Kiss me!". She was giggling, and clearly amused at this new way to fluster adults.
Poor man.
I leaned in and gave her a loud no-contact kiss, which seemed to be acceptable.
