I have had a good weep , there will be more tears.
I’m now reflecting that this is a lot like sending your child off to university.
At first you wonder what they are doing - every five minutes. The house has a huge hole in it and you wait constantly for them to get in touch.
Then, as time goes on, it becomes the new normal and you think about them a few times a day, but you get into a rhythm of contact (Depending on the child - one of mine does video calls at least once a day, the other phones once a week if we are lucky!)
I did this portrait just before he left. I’m going to send for a print and a frame.
