Gee. Good grammar should not be relinquished... especially when paying to have it printed on a sign.
"Think Positively" is correct. "Positive" is a noun. "Positively" is an adverb... it describes HOW one thinks... Or SHOULD think, I think, says the sign. :)
*sigh* Yes... I know that's not your fault. Not counting off for their bad grammar. *grin* |
