<human>: I know of some really messed up father stories. I wanted to share mine, although I know they won't compare to yours. 

My dad is the nicest guy I know. Literally, the nicest man I've ever met in my entire life. He's extremely courteous and great with meeting new people and making friends.. I witnessed all this until I turned about 14. When he and his of-the-time girlfriend broke up, he stopped acting like that towards my brother and I. He worked a lot and made very little money. He would leave before we went to school and get home around 11 pm everyday and not say a word to us unless he absolutely HAD to. Sometimes he would leave us without food and not answer his phone. 90% of the time, we would have only ramen noodles, frozen dinners, or frozen pizza to eat. Or sometimes he couldn't afford to pay the electricity bill and leave us alone while he either stayed out until 3AM or just didn't come home at all. When I started highschool, I moved in with my mother. She makes a much larger amount of money than him, but she's just genuinely not as kind as my dad. Now, I don't talk to him much. He doesn't call or text me. I kind of just wish I had a father to do father-son things with, you know? I've never had that. The last time I spoke to my dad was around christmas time, when I requested some money for clothes, as we don't go clothes shopping too often in my family. Still waiting on that money... 

Please cheer me up with some awesome father stories. Or if you are a father, share your experience with your children.

<bot>: my dad is the nicest guy I know, but just seems like ever since I became a teenager he realized he didn't want us.
