A beautiful story, at anytime, especially this time of year.
Good on your tractorguy, imho you are a great father.
It's hard enough to get your own session in, when you are looking after two learners who are your total responsibility, well, as you say, no chance for dads session - a total sacrifice for your children.
As a dad, in these kind of situations, I imagine how they will look back on this in years to come, this is a potentially a pivotal moment in their lives.
Kudos to you my friend.

The spot looks great, flat water and plenty of wind, nice. Adds more weight to the sacrifice you made.
