Well, the way I look at it is both parties involved put their best face forward when they first meet someone. While showing the best of themselves, if you notice something you don't like, that is a red flag. If seen when at their best, it only gets worse. When someone shows you who they are, believe them the FIRST time
alot and its frustrating me!
An old saying remains true. "Never read a book by it's cover" followed by my favorite "expect the unexpected".
Isnt it also how your perception works, that before meeting the person you have already formed aan image in your mind and then you get disappointed when reality comes through.
