We are often advised to leave work behind the threshold, returning home from work. And how does the Guardian Angel work? I think that after a long day, completely caring about us, he takes off his wings, hangs them on the hook and rest... until the morning...

An angel is generally a supernatural being found in various religions and mythologies. Abrahamic religions often depict angels as benevolent celestial beings who act as intermediaries between
 God (or Heaven) and humanity. Other roles of angels include protecting and guiding human beings, and carrying out tasks on behalf of God. Abrahamic religions often organize angels into hierarchies, although such rankings may vary between sects in each religion. Such angels may receive specific names (such as Gabriel or Michael) or titles (such as seraph or archangel). People have also extended the use of the term "angel" to various notions of spirits or figures found in other religious traditions.
