You know who your Yaya is, but I had a Yaya too. Even your Yaya had a Yaya!
Here's a picture from 2001 of me and your mum with your Yaya's mum Erika, and your Yaya's Yaya Hella.
I loved my Yaya very much; she was a very kind, brave and inspirational person. She taught me many things, but there are three things that stand out:
1. Accept generosity gratefully. It can feel awkward when someone gives you a generous gift, but be careful - the standard overly polite British response of "you shouldn't have" risks devaluing the the gesture. Instead, accept gifts with a big smile and plenty of warmth.
2. Be wary of making your friends jealous. Good friends will support you through life's ups and downs, but when your life is on a high be careful not to boast too much - you might unintentionally touch a nerve and make your friend feel bad about their own life.
3. Respect everything (except authority). Respect is the single most important virtue in life - respect for every single person that you meet, speak to, read about or hear about. Most human problems in history have been caused by lack of respect for others. But always question authority - respect the person not the uniform. My Yaya survived the
Nazi extermination camps, and sadly experienced occasional anti-Semitism even in her old age. She once told me a story about a washing machine salesman who heard her German-sounding accent and saw that she was buying a Braun product, and ignorantly assumed it would be safe to make a horrible comment about it being a shame that the Jews weren't finished off during World War II. Instead of marching off in a shaking rage (which is how I felt at hearing this story), or slapping him, she stayed for half an hour trying to understand why he had made the comment and educate him about what had happened in the war (about which he knew almost nothing). It takes a brave person indeed to respect even those who persecute you.
