I just called, to say… your husband has been admitted to the intensive care unit.

I could sense your shock even over the telephone. I realised you had only left for home a few hours earlier. I wondered if you imagined that he would be the unfortunate 10–15% of coronavirus patients needing intensive care. I wondered if you knew that it took several consultants to decide to bring him to intensive care unit. …

Dear Lydia,

Sleeping peacefully in my arms, you are our ray of sunshine, our bundle of joy, our beacon of hope. Outside our embrace however, the world seems far less hopeful. See, you were born in the middle of a pandemic. COVID19 has ravaged our social landscape, torn apart the fabric of our society, and robbed us of many things we have taken for granted.
