Dude wakes up as a giant bug and spends a good chunk of the beginning of the book not concerned about that at all, just stressed that he's late for work and focused on getting out of bed and getting to work asap lol. It's kind of silly in that way.

Or all the times he thinks he can convince anyone of anything while going up to them and making bug noises at them. Like him approaching them will elicit anything other than terror or disgust at the human sized bug monster. The ridiculousness of it is funny to me.

But it does get much sadder as it goes on and his state deteriorates. Once his family all have to start working and the three strangers move in, the soul crushing feeling really sets in. That and the apple just left to rot in his back.
