I'm going to smoke weed in front of kids
Why do you want to smoke weed in front of kids?
I think it would be fun to do.
Whether the kids belong to you or not, you shouldn't smoke weed in front of them. It is bad for their health, and it sets a bad example. They need to have clean air to breathe and you need to demonstrate responsibility in front of them.
You are a worrywart.
That's not the issue here. You need to understand that you serve as an example to those kids, so you need to show them your best behavior.
