Questions: What does the first sentence mean?

The first sentence, "Someone is asking Grandma to eat with us," means that an individual is inviting Grandma to join them for a meal. It implies a social gathering where Grandma is included as a guest.

The second interpretation, "Someone is suggesting we eat Grandma," is a humorous or absurd misinterpretation of the sentence. It suggests a scenario where Grandma is the meal, which is not the intended meaning. This highlights the importance of punctuation and context in understanding sentences correctly. In this case, the lack of punctuation can lead to a humorous misunderstanding.
