We had a late frost after I poured a garage floor without enough insulation underneath. The ground froze and pushed the concrete up in one corner. It cost me a full day to break out and repour that section. Always check the frost line and use proper base materials in cold weather.
We were finishing a basement floor last week. My sister kept double-checking the edges, which I found annoying. But it hit me that she does the same thing when we plan family stuff. In my experience, that carefulness comes from our mom always saying 'do it right the first time'. It gave the long day a link to home life.
