Reminds me of the classic Erap joke where a reporter asks Erap what his favorite color is. Erap answers "fuschia". But when the reporter asks, "Can you spell that for me, Mr. President?", Erap replies, "Ay, red na lang pala."
For me, the words I always have to spell-check because I often get them wrong are embarrass, occurrence and enrollment. I somehow sometimes think they shouldn't be double letters. So now, I just need to always remember this rule: when in doubt, double (except maybe when I'm spelling occasion or traveling).
