My younger sister is getting spoiled.

As an older brother, I don’t want to see my sister struggling with her school works. Since it is inevitable for students, I pamper her with everything she wants in return for her hard work at school. However, I have observed that she’s getting spoiled through time. She’s starting to ask me expensive stuffs. Three weeks ago, she told me she will be her school’s representative for the national spelling bee. If she will be able to get the first place, she’ll win free tour to Hongkong. And just last night, she told me she actually got the first place. With that, she asked me to buy her a Canon EOS 80D DSLR Camera for her tour which is very expensive for me. I’m so glad for her achievements and will always be but I don’t think it will be good if I buy her one. I realized that somehow, it’s my fault why she becomes a spoiled brat.
