Rober wrote “as same as us,” which was changed to “just like us.” He also wrote “we know that we’ll find each other there as every year,” which was changed to, “we know we’ll find each other there, as we do every year.”
“Like” is a preposition, often used to mean “similar to” or “the same as.” “As” is a conjunction, which connects two clauses. You would use “as” to make comparisons when the second clause includes a verb.
So, in the second sentence, “we know that we’ll find each other there as every year,” is ungrammatical until you add the conjugated verb “we do.” It then becomes, “we know that we’ll find each other there, as we do every year.”
Similarly, in the first sentence, you could add the verb “to be,” so that “as same as us” becomes “as are we.”
Rober wrote, “Each February since 1994 and during three days,” which was changed to “For three days every February since 1994”
There are two parts to this correction. The first is the replacement of during with for. These are both prepositions. Use “during” to describe when something happens: “The festival takes place during the winter.” Use “for” to specify duration: “We were at the festival for three hours.” I also changed the order of the sentence, but wasn’t able to find a concrete rule aside from it sounding better.
The word “fete”
This is not a widely used word in English, and wouldn’t even be recognized by all English speakers. However, while it might be strange to say in conversation, I liked Rober’s use of it here because it fit the playful, celebratory tone of the rest of the piece.
