1. tell your mum that you will be able to retire earlier if you dress from now to retirement as a woman
2. hide the lightbulbs!
3. get her sectioned ( bit drastic though)
4. move!
5. build your own lil tranny shack at the end of the garden and ban her on punishment of death
6. tell her!
7. accidentally burn all your male clothes and ask to borrow her dress, then say, its much more fun shopping en femme, I think I will do it all the time
hope this helps
