Am I Overprotective?

Ok, heres the deal,.. I have 4 year old twins,.. Normally when they play in the yard its in the fenced in back yard.

Now that they have started waiting on the bus(in my front yard) the neighbor's 5 yr old comes over sometimes and waits with them. Not a big deal right?...

Bus was running late this morning, so they start foot races to kill some time, and I know kids like to test adults to find their boundaries. The neighbors boy was all up in the road. My kids were pushing their limits they know how we feel about being in the road. Granted they were only like a foot in the road. Then the neighbors kid wanted them to go across the road, I put my foot down and felt like a restrictive parent.

Im not wrong am I?.... I dont think I am. And since I feel like I make good descisions why ask you?...LMAO.
