英文中DS、DH是什么的缩写?
原文如下：
DS was born on December 17,that's eight days before Christmas.Knowing that I would probably not be up to traveling,I arranged for gifts to go to MIL and SIL with my BILs.I asked them to ship anything for me (and DH and baby) back to us.Christmas came and my BILs told DH that,"Mom wasn't giving any gifts until she saw the baby." I was furious!I was not about to take an eight day old baby on any kind of trip,much less in the winter.I sent my DH up after New Years,and he was told the same thing.
其中MIL、FIL、SIL、BIL分别指mother-in-law,father-in-law,sister-in-law,brother-in-law.
