There are lots of things, but right now these things surely get on my nerves
With hours and hours, my slowest ever computer not getting the internet connection
Exams, just this 1 word is enough to make me heavily sweat
When seriously 'nothing' shows on the TV of my taste
People who unneccesarily boast about themselves
Loud noices, concerts type things in our block (actually currently this is screwing my eardrums!)
