We looked after our.nephew while my brother and SiL were in town recently.
My nephew is what you might call a handful. He threw a lot of toys and food around the room, jumped on the sofas and generally ignored every instruction I gave him.
This was okayish until my DH came home from work. He shouted a very firm "oi" at my nephew as he wouldn't listen. Nephew got extremely upset and was still upset when brother came to collect.
SiL was very annoyed with DH and said we don't tell him no. DH said he'll be told a firm no in this house if he doesn't listen, and that's the end of it. Brother got involved, we had a mini spat and they stormed out.
Brother is no doubt expecting me to apologise but I'm with my DH on this.
Am I right on this?
