Woods overcame difficulties with stuttering as a boy. This was not known until he wrote a letter to a boy who contemplated suicide. Woods wrote, "I know what it's like to be different and to sometimes not fit in. I also stuttered as a child and I would talk to my dog and he would sit there and listen until he fell asleep. I also took a class for two years to help me, and I finally learned to stop."
On December 2, following Us Weekly's previous day reporting of a purported mistress and subsequent release of a voicemail message allegedly left by Woods for the woman, Woods released a further statement.
