I recall when my children were younger...(they are grown now!) my son would spend some nights in the city to fit in with work patterns and at that time my daughter was having marvellous holidays.She has visited China Russia and US as well as much Europe and Scandinavia.One day I just did not know who was here and what day it was (only for a few seconds)Then things get into a pattern and all is clearer.
Our nests are continualy changing.
