So I'm 18

And one of the guys from my school is my new neighbor.my parents are very traditional and I'm not comfortable with telling them if I could have him come over to my house.. next week my mom is going out of town for two weeks and it's just me my dad and little sister.my dad works all day and my sister 13 she can't keep her mouth shut ...

I hate to go behind my family but I really like this guy?

What should i do ?

How can we hangout?

I don't really have any friends that I hangout with so my parents can get suspicious.

So anybody have any idea how I could hangout with this guy ?
