So what I do - is very gently and slowly - push. I push my arm or hand or what ever bit of me she's grabbed - further down the hatch until she finds it uncomfortable and tries to spit me out. And then I hold for a second and let her spit me out.
This is great and works a treat.
I don't need to do it often but I love the look he gives me as he steps back.
"Aww..I did'nt mean nothin by it"
