The best way to remember Ser vs Estar is to use this rhyme. How you feel and where you are, these are the uses of estar!
Thanks for this cute little rhyme :) For followers new to Spanish, Ser and Estar are translated as to be. However in English, we only have one To Be, and so it is very important to understand the difference between the two Spanish translations. This rhyme will help you remember two of the estar uses, but for a good website (my favorite for studying Spanish) here is a link: https://www.spanishdict.com/guide/ser-vs-estar
Thank you Anon for this lovely wake up message (I had snoozed my alarm many times and decided to get up to answer this),
