I wake up in the morning to the smell and sound of rain. I look over to my dog bed and say “good morning Delilah” as I start to stretch. A few minutes later I walk down stairs to see every thing covered in rain as I turn around and start to make coffee. I walk to the fridge to get my creamer and have a great idea to make a omelette this morning. When the coffee is done brewing I pour myself some in a mug and slowing our in the perfect amount of creamer.
