Honestly, I never did that as a teenager. I'm a late bloomer if you will.. but I did#1 but I was so young.. and I learned from it!! Now I'm 23, wonderful boyfriend, good grades, everything so I'm pretty happy. However my two brothers, who are 18 and 20, are those.. I never started drinking until I was 20. My brothers both started at early age, probably 15-16.. so I think it is different with every teenager on the planet! lol..
