Really well done
I have to admit though, that your start was really weak. Animation and detail during that was minimal and the voice-acting and script was coming off as forced. I know you intended for this guy to really come off as annoying and a general attention-whore, but in all honesty, it nearly turned me off from actually watching the rest.
After that vid though, it really picked up from there. Your timing -what with those texts and general plot- was thoroughly well paced, and the animation was incredibly fluid. Little things like the knocking the can off the table, or the scene with the general state of her room, made for great detail too.
Overall, you did good work! I think you could do with someone suggesting quality control for you, since little things like a door-shutting sfx when she leaves, or slightly dripping to the splatter would make excellent touches. Still though, I'm looking forward to where you go with this!
(Oh btw, as an after-thought, I think if someone scrolls down while watching, the sound goes out of sync with the vid. I think you've imported a movie into flash rather than animate in flash, so I don't really have any advice for you here...)
