We can combine these two clauses in two different ways. (using Because and so)
can we change because with so in the following sentence? and Is this applicable on all sentences that have because in the middle (between two clauses)?
Is there any difference in meaning?
We can't go to Julia's party because we're going away that weekend.
We're going away that weekend so we can't go to Julia's party.
Also I noticed that so used more in news website. Is it more formal?
