You shouldn't invade your friend's personal space.
Dave and John are hanging out together at John's house.
Dave wants to find out if John has a secret crush he hasn't told anyone about.
Dave simply asks John if there are any girls that John is crushing on.
Dave sneaks off into John's room and rummages through his things in an attempt to find John's diary.
John is happy that Dave is taking an interest in his love life and tells him that there are none, but he’ll keep Dave updated.
John catches Dave and feels horrified that his privacy has been invaded and feels embarrassed about what Dave might have seen.
