I think we all told our share of white lies, the real question is how do you feel about it. Are they acceptable?
For example.
Today a friend of mine was going to cook something "special" for me, oh and yeah I was pretty excited! Apparently she's been reading up on some exotic cook books and was enthusiastic about testing her new found cooking prowess; me being "always ready to try something new" couldn’t say no. After a nice good wait I was treated to a three-course meal involving a suspicious tomato sauce, a treacherous looking onion covered fish, and a shady casserole, which I never trusted from the beginning.
In any case I tired each one and after three bites from each of the meals I was ready to curl up and die. When she asked me "so what was it like?" I was already in need of CPR. Now usually I would get into a tempered bad mood but strangely I couldn’t get pissed off if I wanted to and instead wanted her to be happy with what she's done so I replied "yeah that’s pretty tasty, your good!" >_<. Of course afterwards there was no way I was going to eat any of that! So after a few awkward exchanges I was off home and my promised "Ice cream treat" wasn’t delivered on!
