     Teen Dating can be fun if you are aware(知道)of its pros and cons and are also aware of the ways

to protect yourself. There are a couple of suggestions you would like to know before you are out for

dating.

     Do not go out for dating with somebody whom you have seen only a few times and does not know

much about him or her.

     Before leaving on a date,know the exact plans for the evening and make sure a parent or friend

knows these plans and what time to expect you home. Let your date know that you are  expected to

call or tell that person when you get in.

     Similarly, if you leave a party with someone you do not know well,make sure you tell another person

you are leaving and with whom. Ask a friend to call and make sure you arrive home safely.

     No matter how good the person appears to you,trust your inner instincts(直感). If a situation makes

you uncomfortable,try to stay calm and think of a way to remove yourself from the  situation without

letting your date realize what is going on in your mind.

     Always stay firm,straightforward and clear in your relationships,thoughts,decisions and judgments.

Never let a doubt come to your mind or face when out for dating. If you are firm and  clear in your

communication,your date will always be careful in dealing with you.

     You should think ahead about ways to be safe if you are in a dangerous or potentially(潜在)

dangerous relationship. Adults,like parents,teachers,counselors,can be trusted in such cases.
