My brother has this habit of looking over my shoulder as I write, and critiquing.
This drives me up the wall for the following reasons:
1) He is 13.
2) He uses phrases such as - 'This doesn't make sense' and 'Do you think this will appeal to a global market?'
3) It is terribly distracting to have someone critique your work AS YOU ARE WRITING IT.
4) He is 13.
5) Though he reads, he is more of a playing football or watching football or playing FIFA kinda guy than a sit down in his room quietly reading kinda guy.
6) He knows it drives me up the wall.
