I don't understand why this would be sad. Unless you know this person and have insight into his situation. I see an older fella making his way down the road. I know loads of old men who spontaneously lose their pants. Yes, it is always funny because it is so random and unexpected. The umbrella is for rain, it can also be used as shade from the scorching sun. It might also be used as a cane. I do not see any of this as sad. Funny, but not sad. Although he looks a bit windblown and disheveled he looks like he is ok. (Please tell me that people are not assuming he is houseless.)
