agree with the above. Haikus are generally considered to be an 'easy' form but actually they are tricky simply because they are short. In a short poem like a haiku, you have to make sure that every word, every syllable is absolutely essential. If they aren't, then you're in trouble. As far as haikus go, this isn't particularly strong but it's not bad.
Also, the repetition of the word thought is not good. But that's already been mentioned.
I say Wolf, for all wolves are not of the same sort; there is one kind with an amenable disposition – neither noisy, nor hateful, nor angry, but tame, obliging and gentle, following the young maids in the streets, even into their homes. Alas! Who does not know that these gentle wolves are of all such creatures the most dangerous! — Charles Perrault
