Let someone go first

I let another car pull out into main street traffic even though I had the right away. I could see that the driver had kids in the van and the driver looked frazzled. After I gestured for them to turn right, into my lane, the driver waved and smiled a large dazzling smile. The child in the back seat waved as well. I was happy to have been able to provide a little less stress to this frazzled driver.
