Sounds like my other half, has a nack of igmoring what he thinks are trivial comments but gets a tad upset if we ignore his. The fact the 6 year old has taken to filling in the blanks is quite humerous at times but clearly annoying.
I walk in a room and say "I'm just gonna stick the dinner on" expecting at least an acknowledgement. Even a smile would do, if he doesnt respond the 6year old will chip in "Thats fantatsic, I'll have chicken nuggets and chips" then OH complains when I cook the nuggets n chips because clearly he didn't seem as bothered about dinner as the 6year old.
"I wonder what we could do today?" I'll say, clearly looking for some nice suggestions for a trip out, even shopping would do. But alas silence until the 6 year old chips in and decides "We are gonna go to Legoland or the Park or Soft Play". Yet he has such a nerve to complain that the 6 year old has more say than him, maybe because he doesnt listen and the child does. I get better conversation from the bairn, and definately way more compliments wven if they are just "Your nuggets are better than Dads" or "Your music sounds really old but it does have good lyrics."
