Little sister is certainly cute. However, I get annoyed by that behavior of not sharing. Maybe it's because I grew up with siblings? It's so weird to me that I let something so petty bother me. I genuinely can't figure out why -- especially since it's just a throwaway moment.
I feel like I'm going to be bothered by the question of why it annoyed me for a while. Not so much what she did... Do I have some sort of repressed mental trauma/event? Why am I even talking still?...
