We never consider those who walk with 4 legs to be leaches when they stay by our side all day and night long; while those with 2 even if they act like they have 4 can make us feel as if they have sucked something out. Why is that we accept our 4 legged friends as loyal but our 2 legged friends as blood suckers? Maybe it’s because we believe even subconsconciously that no 2 legged person should feel so subordinate to another 2 legged being or maybe the 4 legged one’s are just much cuter.
