I feel like you are taking my thought to an extreme as far as being right or wrong. It is not colluding with them to stagnate change. Let's say this issue weren't about words but about touch. What if the T was a hugger and the client hated touch. T hugs client but client doesn't hug back. T decides it must be the hugs so he goes to handshakes instead of no touch (I.e. Mirroring client) or asking and client is still uncomfortable.
