yes, i often hear him making semi-demonic noises of frustration in his room (next to mine) and he bangs on my wall quite often, especially when i won't turn the music/tv down. he got more aggravated when i responded to his texts about the noise level by putting the volume louder, and he he did try to open my locked door in the midst of this, i got angry and he kinda backed down, but continued to send angry texts. i was disappointed.
