Rather than stress it or anything I just went out and bought a new one.
Today, 2 days later, my new toothbrush is missing. Now I'm kind of ticked. Against all reason I decide to call my mother to see if she had knocked it into the toilet or something, idk.
"Yeah I inadvertently thought it was mine so I packed it in my bag to boston."
Okay, firstly you don't inadvertently think something is yours. There is no unintentional thought process that goes into grabbing something and defining it as yours in your mind. Okay, you may have been MISTAKEN but it wasn't inadvertent.
Secondly, the toothbrush is grey. There are 5 toothbrushes in this house. 3 are purple, hers and 2 are blue, mine. One of my BLUE ones went missing so I got a grey one because it was neither blue nor purple (and to avoid any bullshit adaberk situation) so there's no WAY someone could have fucking goofed on it. How in god's name do you think that a toothbrush you've NEVER seen in your life in a color NO ONE in the house uses is yours? WHAT?
