"For me, it means..."

For me it was not one specific meeting, but rather a series of meetings with a customer over some years.

It was like the movie "groundhog day", it was the same all over again.

We had this technical term, and our customer had his own definition of what it meant and what it's supposed to be. No need to say that his definition did not match the one the engineers and developers of the world had agreed on.

At least a dozen times, i convinced him, but as soon as the meeting ends, it's all reset and we start at zero next time with his new or old definition of what a definition should mean. Sometimes i was just sick and tired of it so i let him explain how it is while i just stared into the void. Didn't matter he told me once, it will happen again next time again, like it never happened before.
