For he hath given his angels charge over thee; to keep thee in all thy ways.
Quoniam angelis suis mandavit de te, ut custodiant te in omnibus viis tuis.

In their hands they shall bear thee up: lest thou dash thy foot against a stone.
In manibus portabunt te, ne forte offendas ad lapidem pedem tuum.
-Psalm 90: 11-12

I strongly suspect that we will all be mightily embarrassed when we are shown just how much our guardian angels have done for us, how many times they have saved our skins, how much they love us, and how little we acknowledged them. Make sure you acknowledge your guardian angel today, most especially.
