Why would someone keep a high physical distance to a certain person?

Anonymous

Assuming the person does not smell and has good hygiene. A guy once almost bumped into me when he leaned over my shoulder from behind to look at my screen (his cheek was almost touching mine). Now he tends to stand far away from me when we talk and almost acts scared of me. What is his problem?
