Fraternal Support

I knew my sister was desperate but not that much.  She was very sad after his recent divorce so I decided to host her at my house for a few days. One evening, seeing her more sad than usual I said I would do anything to make her happy.
The next morning I awoke with a strange feeling, I got up and a waterfall of black hair covered my face. I run to the bathroom mirror and I didn’t believe in what I was seeing I was my own sister!
On the kitchen table I found a note, it said:
 Dear ex-bro now sis, thank for being so close to me these days I realized that  you always will be the only one man in my  life so I thought that I would like to be you.
You didn’t know but this year I’ve learnt  the magical arts so I decide to make my 
wish real. So thank for all and goodbye!
p.s. I hope you would have  better luck with men!
