A couple of items that make me cringe, but I bite my tongue rather than saying anything that might offend – Take the log out of your own eye before removing the splinter from someone else's and all that, I am sure I say many things that make others cringe as well, to say nothing of my unfortunate condescending tone of voice.
Starting a sentence with "Me and…", it seems that this is even taught in schools on the othe side of the pond. Whatever happened to self deprecation, listing everyone else first and placing yourself last – I suppose this is possibly an extension of the "Me first" culture we see on the roads.
Ending every question with "Isn't it?", "innit?", or "you know what I mean?", hardly any questions need these additions.
Excessive use of the word "like", sometimes every other word, as filler by people who enjoy talking incessantly.
I fully appreciate that many people may not have English as a first language, and my attempts to speak their native language would be laughable, but I regularly hear all of the above from native English speakers. I am forever having to remind my own children not to use 'like' and either pause, slow down, or try to use an alternative word. I was taught to avoid using "get", "got", "nice" and "like", as these are lazy words and to try to use an alternative if possible.
There is a current Green Flag advert being broadcast on the radio that talks about "bucket fulls" of something as opposed to "buckets full", I cringe every time I hear it. I appreciate that not everyone is great at pluralising, but if something is going to be broadcast nationally, at least have the script checked first.
