60% cool. 40% you

i'm a bit ashamed of the fact that a few weeks ago i told my husband he was only 60% cool.  yes, it was in reference to his tattoos - but none the less it was the wrong thing to say.  as i've thought about my comment i've aquated it to the age old question (usually by a women), "am i fat?" to which the right answer by the significant other is, or at least should be, "NO, your beautiful and i love YOU!".  so, why in this moment did i feel the need to say what i really felt?t
