So if this <code>ratio</code> is too high like 2.0 or 1000.0 or too small like 0.1, it means the updates between consecutive policies are too drastic.

| │ POST: Hi, │ │ │ | |
| │ I'm 22, and I have been with my │ │ │ | |
| │ girlfriend for 5 years now. We │ │ │ | |
| │ recently moved together. We've │ │ │ | |
| │ always loved each other │ │ │ | |
| │ intensely. │ │ │ | |
| │ │ │ │ | |
| │ Problem, I recently started to │ │ │ | |
| │ have feelings for an other │ │ │ | |
| │ person (a friend). This person │ │ │ | |
| │ has had a boyfriend for now 3 │ │ │ | |
| │ years, and has absolutely no │ │ │ | |
| │ ideas. Those feelings were so │ │ │ | |
| │ strong, it was hard to hide │ │ │ | |
| │ them. After 2 months of me │ │ │ | |
| │ being distant and really sad, │ │ │ | |
| │ my girlfriend forced me to say │ │ │ | |
| │ what was bothering me. I'm not │ │ │ | |
| │ a good liar, and now she knows. │ │ │ | |
| │ │ │ │ | |
| │ We decided to give us a week │ │ │ | |
| │ alone, I went to my parents. │ │ │ | |
| │ │ │ │ | |
| │ Now, I'm completely lost. I │ │ │ | |
| │ keep on thinking about this │ │ │ | |
| │ person, and I hate that. I │ │ │ | |
| │ would like for those feelings │ │ │ | |
| │ to go away, to leave me alone. │ │ │ | |
| │ But I can't. │ │ │ | |
| │ │ │ │ | |
| │ What do I do? It's been 3 │ │ │ | |
| │ months now, and I'm just │ │ │ | |
| │ desperate. │ │ │ | |

| │ POST: She was in her living │ │ │ | |
| │ room, watching TV. This was at │ │ │ | |
| │ about 8:30 in the morning, and │ │ │ | |
| │ she was exercising. She turned │ │ │ | |
| │ the TV up extra loud to hear it │ │ │ | |
| │ over her excercycle, and woke │ │ │ | |
| │ me up. I went in there asking │ │ │ | |
| │ for her to turn it down. She │ │ │ | |
| │ said she didn't have to; I │ │ │ | |
| │ explained that I always used │ │ │ | |
| │ headphones so she didn't have │ │ │ | |
| │ to deal with my noise and that │ │ │ | |
| │ she should give me a little │ │ │ | |
| │ more respect, given that I paid │ │ │ | |
| │ rent at the time. │ │ │ | |
| │ │ │ │ | |
| │ She disagreed. I went back to │ │ │ | |
| │ my room, rather pissed off at │ │ │ | |
| │ the lack of equality. I had no │ │ │ | |
| │ lock on my door; but I had a │ │ │ | |
| │ dresser right next to it, so I │ │ │ | |
| │ pulled one of the drawers out │ │ │ | |
| │ enough so that it caused the │ │ │ | |
| │ door to not be openable. Then, │ │ │ | |
| │ I turned my speakers up really │ │ │ | |
| │ loud and blasted Gangnam Style │ │ │ | |
| │ on repeat, with the bass │ │ │ | |
| │ cranked up as high as it could │ │ │ | |
| │ go. │ │ │ | |
| │ │ │ │ | |
| │ If you hate Gangnam Style for │ │ │ | |
| │ being overplayed, you will see │ │ │ | |
| │ why I chose that particular │ │ │ | |
| │ song. I personally don't mind │ │ │ | |
| │ it. But here's the thing about │ │ │ | |
| │ my bass; it vibrates the walls, │ │ │ | |
| │ making one hell of a lot of │ │ │ | |
| │ noise. Needless to say, my mom │ │ │ | |
| │ was not pleased and shut off │ │ │ | |
| │ the internet. But it was oh so │ │ │ | |
| │ worth it. │ │ │ | |
