We all.
I have got into trouble on Gransnet twice for becoming ratty about someone writing "we all" in a post. The first was a bit of a spit when I encountered yet one more welcome to a new member with "We're all as mad as a box of frogs" or some such thing – having just read three other similar comments. Speak for yourself. The second was more recently and concerned a far more serious subject. It seemed to me very wrong to suggest that the unhappy family situation being discussed was the norm. It certainly didn't apply in my family However this was just Gransnet.
Journalism and the mighty BBC are another kettle of fish. A few weeks ago on Breakfast television (and the News Channel also often uses the same scripts) there was a piece about How "we were all inspired by the Olympic and Paralympic athletes". Well, I for one wasn't 9I didn't watch the Olympics) and nor, judging by the queues outside Gregs the bakers, were quite a lot of other people in this town. In the same bulletin they talked about how "we all" had watched with amazement that chap who did the sound barrier freefall/parachute jump. I didn't/haven't seen it.
We are bombarded with this lazy journalism. "We are all overweight", "We all eat to much salt", "We all take too little exercise" are three phrases I have read in the last week. "No we all aren't/don't," she screamed.
