He woke up and said he didn't feel like it
I was positive and said 'look it's a dry day, you have a party later etc'
So I messaged the ex and suggested that he could do the Sunday morning rugby as he's good at the motivational pep talk etc
He rang and spoke to Ds who ended up crying and going back to bed 
I've text his coach and apologised and asked if he could maybe have a word with him at training
I was never a sporty child so I can't really get into making him go.
He does a lot of sport and is also a bright child who works hard in school
AIBU to not force him to play today?
