personnally ive found that since i started smoking i have been spacing out a bit so i wouldnt drive (not like i can) but i feel as if theres no need to talk back. normally my mum makes some really stupid comments like
im playing games
mum: are you playing games?

or somthing to that effect and normally i would say somthing back but i just let it be i say thanks and please more. maybe its cos im getting older but thats what i noticed. its probly has nothing to do with it but meh
