Context is Important

A short while ago,  I corrected a sentence in an entry after I read the  entry a few times to understand the sentence.  The sentence is as follows: "My wife told me not to go to the gym today, so I worked at home." A native English speaker corrected the latter part "I worked at home" to "I worked from home," and another native English speaker voted to the correction, but I thought it was strange that talking about a gym in the first part and suddenly talking about woking from home. I changed it to "I worked out at home." I suppose the author wanted to say that. Even if a sentence is grammatically correct, sometimes it does not match the content, so we should be careful when making corrections.
