I am used to being alone at night, because the hubby works at night...but with him out of town, for this long, I am always a little more leary...tho, I have had to learn to cope with him being out of town, not just on his travels...when he was in the army, he was always out of town, either TDY or field trips, or summer camps...
But no matter how many times he goes away, and how used I am supposed to be to having him gone, I am always thrilled when he returns...
You are right, having our hubbies at home, makes the home more warm..
