When people are tired of being in a place locked up all day for different reasons, what causes them is to run out to an outdoor place where they feel free; However, there are people to whom this type of place causes them some anxiety or panic. These are known as Agoraphobes that derive from Agoraphobia. Now the word agoraphobia is the irrational fear of open spaces, such as squares and wide avenues, and comes from the Greek: ἀγορά agora = assembly, public square, market, discourse, and φοβiα phobia = fear.
