In most simple English sentences with a prepositional phrase, one change the position of the phrase without a significant change in meaning.
Because of the weather, Peter went home.
Peter, because of the weather, went home.
Peter went home because of the weather.
On the other hand, the position of phrases using the preposition ‘unlike’ can be crucial when negation is involved.
Like David, Peter is not a farmer.
Peter, like David, is not a farmer.
Peter is not, like David, a farmer.
Peter is not a farmer like David.
The meaning depends on whether the prepositional phrase appears before or after the ‘not’, which I thought was interesting.
