I stuttered from about the age of 7 yrs old until I joined the programme in 2001.
Being a covert stutterer, it took me some time to acknowledge that I was a stutterer.
On a one to one scenario, I could cope reasonably well, using tricks, avoidances, and substitutions.
Within a group, I hid it reasonably well, but was only fooling myself.
I could talk to myself, animals and small children, anything that could not determine that I was a stutterer
