I am sure that many of us can understand this, and have had our own "little things" that annoyed us so much...but that we would long to have again now! When my son was little, I often stepped on either a small toy or a Lego (while barefoot of course). Needless to say, it hurt and I was annoyed! Now that he is almost 18, and not that cute little crazy-haired boy anymore, I too find myself longing for those days of strewn toys across the floor! Someday soon, he won't be living at home anymore, and I will long for those days even more!
It is difficult in "the heat of the moment" to pause and think about what really matters. But, if you can, you will definitely look at things differently! There is such truth in the quote, "Pick your battles wisely". Some of those little annoyances, don't really need to be brought up. It has taken me years to learn this, but thankfully I have...and it has made all the difference!
