Reciprocal Actions

"(to) each other"
What are RECIPROCAL ACTIONS???
       When you are trying to talk about doing something "to each other" ..use reflexive pronouns like 'se' and 'nos' to express idea "(to) each other" You place the 'se' and 'nos' before the verb and conjugate the verb to whatever the subject is. This is expressing that the subject is "(verb-ing)" to each other.

Ex) Los novios se abrazaban y se besaban.
     ...The bride and groom were hugging each other and kissing each other.

Ex) Por lo general nos sauludabamos con un abrazo. tambien nos dabamos la mano.
    ...We usually greeted each other with a hug. We also would shake hands.
