If I Go Missing

One way that I entertain myself at work is by ignoring the Spanish teachers' attempts to make me speak Spanish.  I don't correct their grammar, so why do they feel the need to force me to speak a foreign language in their presence?  It usually goes like this:  "Hola, chica!  Como estas?"    "Hi.  Fine.  How are you?"  They get so pissed!  So funny.  But they never give up. 

Anyway, one of these annoying Spanish teachers has now switched to annoying history teacher.  Somehow I've been living a few streets down from him for the past year and a half and didn't notice it 'til he saw me take his exit a few weeks ago.  He told me last week that he put his kid and wife in the car and actually admitted to driving down my street to look for my car because he wanted to know where I lived??  WTF? 
1) Why would you do this?
2) Why would you admit to doing this?
3) Why would you add the detail about bringing your family with you? (Maybe because you know how creepy you sound?)

¡Ay caramba!
