Routine events: reflexive pronouns 'me' and 'te'

The 1st person singular (I) of regular -ar verbs like 'lavar' ends in -o, the 2nd person singular (you) ends in -as. Some Spanish verbs like 'despertar' have a stem change -e to -ie in some forms. For example: 'despierto' (I wake up). To say that I do something to myself in Spanish we use the reflexive pronoun 'me': 'me presento' (I introduce myself). To say that you do something to yourself, use reflexive pronoun 'te' before the verb: 'te llamas' ('you call yourself'). The reflexive pronouns 'me' and 'te' look similar to the possessive pronouns 'mi' and 'tu' but they are different.
