It's a sign

I think the universe might be telling me to concentrate a bit harder. Especially when I'm driving.

So far, in the past week and a half, I have almost hit:

Two bike riders
Two children riding their bikes on the footpath out the front of my house
Two joggers crossing the road at a T intersection near my house.

I wonder if the two is significant as well?

Does it mean I have to concentrate twice as hard?

Or is it just that I have to slow down and look a little harder?

Either way, something tells me I'd really better be careful.
