I had been having trouble with the lock on my front door. I had even left it unlocked a couple of times. I decided to try to fix it myself before sending an SOS to the handyman (AKA my brother, who lives an hour away). I removed a couple of screws so I could see the inner workings. I had forgotten to see if there were screws on the other side. I went out through the garage to check. Nope. I picked up the oil on the way back in. I oiled the inside of the lock and put it back together. It worked like a charm. I was proud of myself. I felt relieved my house was once again secure.
In the morning I went out to get in the car and head to school. The garage door had been up all night.
