person A: My biggest pet peeve is litterbugs. I want to go up to them and scold them for not respecting the environment.
person B: I completely agree!  I am all about keeping the earth clean_comma_ recycling_comma_ and low waste living.  They should get bigger fines!
person A: Yeah_comma_ maybe someone should litter in their house so they can see how it feels. And don't get me started on cigarette butts...
person B: I'm right with you.  Oh_comma_ cigarette butts gross me out_comma_ not to mention second hand smoke which has been found to cause cancer too.
