<human>: So I have known both of them for years and we are all really close friends. I have played with the thought of a relationship with her but nothing came of it. Recently I have been noticing things like prolonged eye contact, being more quiet around me, and even laughing at my shitty jokes. She is really sweet, really pretty, and shares interests with me.

So, I guess what I'm asking is, should I go for it? If so, how do I broach the subject with her brother? The entire family is pretty laid back, and super friendly. The more I think about it, the better the idea sounds.

Give me the gist of the text in a nutshell
<bot>: I'm interested in the little sister of my best friend, and I think she is interested in me. What do?
