What we learned from this movie
1. Do not use a big apartment building that does not belong to you for a romantic thing (especially after the old man who lives on top floor that you inspected earlier in day mentioned that people are breaking in to get him).
2. Do not forget your cellphone in the car.
3. When you find the old man dead in his apartment use your cellphone to call 911 not to call your boyfriend.
4. Turn your ringer off right away.
5. Do not be dumb enough to drop your phone off of stairs.
6. Climb all the way down the drain pipes when you have a chance.
7. When you are in old man's apartment after bad guys went downstairs and they do not know you are inside...find some knifes in the old man's apartment that you can use as weapons later.
