If my wife works late. Is it better for me to wait for her, or I should light בזמנו?
My wife is not מקפיד
I just feel to light with nobody home has no advantage
Wait for your wife to get home, (and she should come home as soon as she can). even though she says she isn’t makpid she really wants you to wait for her. We see from the gemora that shalom bayis in certain ways, takes precedence over ner chanukah.
A freilichen Chanukah
