Well, dont.
To the person who accosted my husband this afternoon in the Kingston Waitrose and harassed him loudly for ruining the planet by buying some pajama pants: what on earth did you think you would accomplish by this? "oh right, this unpleasant shouty stranger must be right, I shall abandon the errand my DW sent me on immediately and go home and convince her of the benefits of daily sleeping bag laundry on our camping trip?"
If you want to vent, come here. If you want to change the world, join WEN or friends of the earth, or do good works.
And btw shouty lady - I wore out my MEOS until they were threadbare - I and my DH are not your enemy.
Whew, just had to get that off my chest.
