How do you deal with a HB's sister if she is protective?

Im just curious cause this is my current situation right now with an HB I met. So far I get along pretty well with the older sister, so I just need some perspectives. I am just going to put a number of questions. You guys are welcome to answer all or part of it. I want to make things interesting and usefull for the rest of people reading this.

Should you look like a good guy in front of her when youre around the HB? Should you just ignore her, work your game and try to isolate HB?

Is she useful? maybe doing something which could potentially en up encouraging you to hit on her sister? or using her to make HB jelous and want you more?

Should you try and get her out of the picture or is she useful?

I would appreciate some description as well if possible, explainning how. Thanks

aanyone? lol

there's not enough info here.

In any case, if the HB is interested in you, you should use HER to disable her sister.

If she isn't even strong enough to keep her own sister in check, issues are going to arise later on, no matter what you do to remove the sister yourself

Good point spicex

thing is that i didn't find it necessary to add any more info because I wanted to know in general how to deal with a protective older sister. And if maybe I can find her useful by somehow using her to get the hb more interested in me maybe?

I dunno its just a general question which I wanted to know if theres anything I can take advantage to apply in this situation, in order to make my game easier.

If you already get along well with the older sister, just keep doing exactly that. No need for fancy tricks here.
