Tone and Mood

Tone

The tone is accusing and complaining yet understanding and teasing at the same time. There is also a mixture of amazement and mischief in the tone; amazement at how Mr. Nobody manages to accomplish everything without being noticed and mischief at how everyone knows who Mr. Nobody is. The persona mentions all the mischief done by Mr. Nobody. They know who the culprit is yet dont want to pinpoint the person. The persona sympathizes as well as empathies with the family for having to put up with the mischief. At the same time, the persona understands that this normally happens in every home. 

Mood

The mood is humorous.
