I often go shopping by car. I sometimes drive to work. My husband also uses the car. We have one car and two keys. One key is my key and one key is my husband's key. But right now I don't have my key.

I have lost my car key. I have been looking for it since last week. It stands out because it has a big, red key ring on it. But I can't find it anywhere in the house. Now I borrow my husband's key to drive, but I feel uncomfortable because I can't find my key.
