I used to always tell T no when he wanted to try something new and I would refuse to even attempt it. When I did, I just said, "It didn't work." T has been patient and accepting. I think part of it was an attempt to feel safe--trying something new is scary. And a big part of it was me testing T to see how I reacted when I said no. He was always accepting and respectful. It got easier to take risks and say yes.
