The same reason there's any other couples...they like/love each other.
by speaking to each other
in a way yes they lie to each other when they are speaking to each other but all we here is some squiking noises and that is when they are talking to each other!

I'm guessing you are a young'n Couples lie to each other often. its part of human mentality. It comes down to the weight of the lie.. Feeling guilty and fessing up about the lie is bout all u can do, but u need to look at how big or small of a lie it is. IE: Yes honey your butt doesn't look fat (when it does) don't admit that was a lie. stick to it
No, its your life authorities don't have any control over underage couples staying the night with each other.

Couples kiss because they like each other, and have deep feelings for one another.
The same things heterosexual couples are "characterized" by. Couples, regardless of the sexual plumbing, are intimate friends who share secrets, worries, triumphs and problems. They work together to make their lives together richer and more satisfying. They care for and about each other. They encourage each other to do more and be better. They stand up for each other, listen to each other, comfort each other and work to make their relationship stronger.
because that's just how couples are sometimes and because they love each other :)
As an expression of their love and commitment to each other.
