smoking under age

I was at my cousins house and it was at night, I was sleeping over because it was like a long time . So then we all was having fun until 3 or 4 of my cousin head out side. I asked them, “what are you guy’s doing” and they told me that their smoking. That was the first time i saw my cousin smoking especially one of my cousin who was the same age as me but was a year older than me. That just made me sad i knew even if i try to talk it out with him it would stop any thing so just didn’t because all of his bigger brother smoke and thats what making him not stopping.
