Coffee

My coffee has its own personality. Normally it is adorable. But today I saw its dark side. I like coffee. I was addicted to the caffeine and am trying to restrict my caffeine consumption to one cup of coffee everyday with three or four cups of tea. Today I gave myself a right to have two cups of coffee. The first cup was normal. Adorable. And yet the second cup was so bitter. Harshly bitter. I am quite sure I put the same ingredients and similar proportion. Could not explain why the results were like south and north. Warm south and cruel north. It seems like today my coffee tried to show its dark side personality.
