Let's get a bit more familiar with each other before you invite me to your house.
应该很好理解了,不确定再追问我吧.請問這樣可以嗎?Let us get a bit more familiar with before you invite me to your house.如果用了介词 with 后面就必须加 each other但是全都省略了也行，尤其在口语中都是力求简洁的。Let us = Let's口语中极少拆开Let's get a bit more familiar before you invite me to your house.意思已经够完整啦。
