Could you say "oss" in place of "vi" here?
Is there any kind of usual order, adverbs of place and adverbs of time?
Late answer: I wrote a little about the order of adverbials here, under 1.1, but it's a complex issue. https://www.duolingo.com/comment/8970470
I would think it would be "us" and "oss".
It should be "than us", not "than we".
