Instead of heading to the library after dropping AB off at school, I went back to the apartment and did mydomestic duties (laundry, dishes, putting away toys, etc.). Basically, I did all the things that are incredibly frustrating to do when she is around and that I am too tired to do once she is asleep.
I have come to the realization that I do enjoy doing these things, especially laundry. (It is very calming and satisfying to fold clothes fresh from the dryer). I cooked dinner yesterday and actually had fun while doing it.
I only feel this way because it is just the two of us. Throw another adult into the mix and I guarantee you that I would not be feeling so rainbows and butterflies about it.
