Because I was lazy, I was early for work today.
I was lazy yesterday and did not wash my coffee pot. So when I got up this morning at my normal time, the time that gives me time to make coffee and make breakfast and do a little surfing before work, I could not make coffee.
Instead I showered and shaved and got dressed early. Then I was still hungry, so I headed out to a coffee shop to get some coffee and wake up.
Having done that, I took the bus to work. Where I was early.
