do you need a bag?

i thought i love this earth. i thought i have been a good person. i think i havent been a good one. not yet. i realized most people bring their own bag to shop. and usually, the cashier will ask, "do you need a bag?" i think that question is weird. at first. not until i went to marks n spencer food. i bought the bag, because its MnS. back in malaysia, MnS are expensive. people look at people bringing or wearing MnS with envy. that was before. then, i went to asda td. and i bought this asda bag. it is stated on the bag, "i do not cost the world". something just click. yeah, i have been using plastic bag, which is chemical. why dont i use my own bag before this..to carry my stuff. wouldnt that be handy, or fruitful. for i wont need to use plastic bag. and that will reduce litter. hurm.. since that, ive been carrying my own bag, and reuse it as many times as i can, to help this earth. i love my earth. i love our earth. "do you need a bag?" "no, thanks, ill use my bag.."
