I agree with the 'positivity is the key to happiness' comment, that's why it doesn't make sense for you to say we can't change things.
Even when you only do something as small as explaining to the woman at table 6 why veal isn't on the menu. Maybe she hadn't known before that.... maybe she won't feel so good bout eating it again.

Do not overlook tiny good actions, thinking they are of no benefit;
even tiny drops of water in the end will fill a huge vessel.

Do not overlook negative actions merely because they are small;
however small a spark may be,
it can burn down a haystack as big as a mountain
Lulu Reviewed by Lulu on . The Chicken Killers!!! Man, that is the LAST time I ever do THAT job :( I had to drive a lorry to a chicken farm last night, and collect some chickens for slaughter. Geez, what an eye-opener. There were these sheds (about 20meters x 80meters), and the floors were covered with live chickens - like a carpet! There were 5 sheds. They are kept in these sheds from hatching to about 40days old. Their light is artificial and set to timers. In other words, the only true daylight that they see, is in the back of the Rating: 5
