One of the questions I've been pondering about when it comes to comics is, when Peter Parker got his powers, why didn't his fellow students at school figure out Spiderman's identity? Shouldn't Pete's schoolmates be able to figure things out when Peter suddenly goes from scrawny to athlete in like a week simultaneously as a new superhero shows up in the city? I never read the earlier Spiderman stories so I never got a good explanation for this. Did Peter stay away from school as sick leave for a time because of the spider bite, claiming that he worked out during that time? Or did he skip going to the showers after physical training before and/or after he got his powers to avoid the bullies, so no one actually got a good look at his physical shape? I know Kong figured his identity out in the Ultimate universe, but he seemed to be the only one. How did Peter manage to keep his sudden physical transformation unnoticed during his first time as Spiderman, or at least unnoticed enough to prevent people from figuring out his superhero identity? Did he make arrangements at all to conceal his new superhero identity or was it just plain luck that no one noticed?
Please don't reply "because it's comics", surely there are more creative ways in which this could be explained.
