My friends smoke everything!

A couple of my friends asked me if I wanted to come to the park today. I asked my mom, she said yes, so I went.

I texted one of my friends, to see where they were, cause I didn’t see them at the park. She texted me back, she said they were in the trees. Then I see her come out of the trees waving her arms around like crazy!

So I go into the trees with them, and I see weed, cigarettes, bongs, stumps, and a bunch of lighters everywhere. Then they ask me if I wanted some, I said no, and so they said OK

They respected that I didn’t want any, but I don’t really like how their only 12-13 and smoke everything! If I say something to them like, I can’t believe you guys did that! they’d say, so? its not like our parents’ll find out!

I stayed for a couple minutes, then I went home all freaked out! I always thought they knew better than that!

How can I get over this phase in my life?
