How can you be slave for a girl?

Just ask her if you can be her slave, works all the time. Or, if you hang out together, you can do everything she says and then she knows what you are doing. Do things like:

1.ask if you can carry her stuff like her purse or, if you are at college, schoolbooks.

2.hold doors open for her.

3. ask her what you have to wear next day, she will look surprised but she will say what you have to wear.

4.always say that she is right. Never say the different.

5.if she is busy with something she doesn't like, do the work for her.

If you do this things, she will except you as her slave and you didn't ask her to. And if you are: always do everything she asks.
