“We are not used to visitors after dark, but you're welcome here.”
我们天黑后不习惯有客人来,不过还是欢迎你。
先划出界限再给客人台阶,一句客气话里全是戒备。
We are not used to ..., but you're welcome here.
不想被突然打扰、又得保持礼貌时用;对朋友说会显得生分。
We don't get many visitors this late. / You're welcome, though we keep early nights.
中性
not used to 放平,you're welcome here 微微上扬。
We are not used to guests after ten, but come in. 我们十点后不常有客人,不过进来吧。
