I can't wish everyone a Happy Cinco de Mayo, because we know it's not. The H1N1 virus, the shutting of tourism in Mexico, life as we know it shut down in Mexico; so, as a result, this is not a Happy Cinco de Mayo in Mexico and/or here in the United States.
So, no wish for one this year. I have a Spanish blog I've just started last month and it is a shame to not wish everyone reading a happy Cinco de Mayo. No historical reference to it; nothing. But, maybe next year I will get the opportunity to do so.
