I called you several times, but you didn't answer me. Where were you? I was at home, listening to music.

[In this situdation, can we use both sentences? Are both the same in meaing? Which one is commonly used?]
1. I was home, listening to music.
2. I was at home, listening to music.

Yes, both sentences are fine. #1 is probably used more often than #2, but I think it'd be a toss-up!

Both sentences are grammatically correct and convey the same meaning; however, the first sentence, "I was home, listening to music," is a more colloquial and informal way of expressing the idea. In contrast, the second sentence, "I was at home, listening to music," is more commonly used and considered more standard in formal or written English.
