Never judge a book by its cover

Arrgh!!!! I am so angry! Finally realised the term "never judge a book by its cover", and its like "Charlene, welcome to the real world!" I am still fuming... Angry and provoked... How angry was I? To the extent that I almost swear! Now you can imagine my anger cos I hardly ever swear at all!!! Grrr....Anyway, I realised that the more quiet, decent and nice person is, he can be the worst of all... No longer going to put my trust in all these people (except for that 1 or 2)... This people can be the ones that provoked you the most... I am so angry and upset that I am taking it out on potato chips and peanuts now. They ain't good for my skin and body but they are my outlet for frustration! Arr!!!
