Good question op
Hmm, I remember my childhood was and probably will be the happiest time of my life. If I could go back and relive it I would. I can't pinpoint one exact memory but all I remember is how carefree and innocent I was. My mother used to let us roam freely and we'd get up to all sort.
I think seeing my mother and grandmother bonding was always something that made me feel happy. My mother wasn't raised by my grandmother she always felt like she was unwanted by her parents which wasn't the case at all. But it's understandable why she felt that way.
When I passed my theory driving exam I was extremely happy. Also finding out my younger sister got accepted to go to the university she wanted that was a very happy moment. I cried when she rang me and then she put the phone down on me because I was doing the most lol.
Can't think of anything else.
