Superheroes also have sad days...
Not every day is a happy day for our super heroes. They have hard days like everyone else. Batman seems in a good mood, but his buddy Spider man does not.
I don't remember what the cause was.... maybe there was an ungrateful person that he saved? ... maybe it was just one of those sad cloudy days... We will most likely never know... because the life of a superhero is a lonely one....
Be Strong Spider man!!! Just 47 more years until you can retire!!
