Aishu deserves some apology from me. Do you agree too?

In my previous post, I shared that I read the plot of the 2013 romantic movie Aashiqui 2 and almost tears came in my eyes as it was very sad movie. I was thinking about Aishu a lot after reading that. As you all know Aishu was my childhood friend when we were in elementary school in 2008-2011 and now she is 21 and I turned 22 just over 3 weeks ago and she is only 5-6 months younger than me. Even though in our elementary school days, we used to play together, study together and have sleepovers, we used to fight too. I remember 3 such incidents for which she deserves an apology from me and these happened when we were in 4th grade. They are
1) I remember she had a globe and we were fighting because i wanted to take her globe to my house for one day to play with it but suddenly during the fight the globe fell down from the staircase and it got damaged and broken. She ended up crying seeing that.
2) I also remember seeing her having a pencil box which had so many buttons. I wanted to play with her box but she wasn't giving it so I got angry and tried to snatch it from her and we were fighting and the pencil box fell down and it broke. She again cried.
3) This was a bit worse than the above 2 because it was when my mom was dropping me and Aishu to school and we both were arguing about something and calling each other names but suddenly she called me a donkey so I got angry and pushed her and she fell in a muddy puddle. My mom scolded me badly and she was crying and she had to change her dress.
I know i was still a kid who was in 4th grade so its normal for kids to be that way but we are pretty much the same age so I feel like apologizing to her for making her cry so much those days. I did say her sorry those days but it was forced because my parents used to tell me to say her sorry but now I wanna say her sorry with my heart. I really wanna meet her and apologize and get closer with each other and never ever fight again. We chat on Instagram but not regularly as she replies mostly on weekends.
