Because you have been a very good nurse.
You have chosen the smallest needle whenever you could. You have made all the postural changes without complaining. The heel protections turned out very cute. And you have never (or rarely) cursed your supervisor. For that and much more, Santa Claus is going to be good this Christmas. Of course, ask him with love. Ask him with this letter apurada. It surely works.

Quick Tips for Printing:

• Print in A4 size, double-sided and in color.
• Ideally on paper of about 200 grams, so that it remains nice.
• If when folding along the lines to close, it does not fit well, cut a little more at the bottom, where it says "Enfermera en apuros."
