My son thinks he has established the cause of his upset.
"I know Mum can't live here anymore and she has to live in Heaven. But can't she even come back just for a hug?"
I admit it. There's nothing quite like a hug from Mum and as much as I pride myself on the high quality of my hugs, I can't give him a Mum-style hug. He cuddles my sister a lot.
"I'm sorry... she can't."
"I know she can't. But I'm still sad."
But hey... we all feel like that sometimes, right? Sometimes we all just need a hug? From Mum.... from girlfriend, boyfriend, best friend, someone you miss.
So here's to hugs :)
