Funny grammar mistakes that changes the entire meaning of a sentence.I came across an example where missing a comma changes the entire context. Please read the following sentense without any punctuation.
Let's eat grandpa.
This says that the speaker wants to eat his grandpa. But the conversation is completely different where he is calling his grandpa to eat together. Read the sentense now.
Let's eat, grandpa.
Hence it is necessary to make sure we add correct punctuations. Sometimes, it may not make much difference but sometimes it gives a wrong meaning.
