Joel's work was equally, if not more, exhausting. Patients, papers, patients, papers, gotta have patience with the patients....arghh!!! "I'm just trying to catch some air" was one of the first things he said to me when I picked him up at work. I saw him do the sigh-smile combo while wrestling with Joe. I guess that moment did it for him.
And before his litany of "ba-ba-ba-ba-ba" as I help him get to bed, Joe tends to heave a sigh. I can tell he is happy and content as he talks out the day's events and sings along to his lullaby. After a tough day of crawling, growing, and playing, he must be glad to get some rest.
Relief in the form of a **sigh** comes naturally after doing a full day's work--so should a smile be equally appropriate after realizing all that you've accomplished. Sighing out.
