Childish Mistake

When I was in primary school there was the plastic bracelets that came in different colours, the blue one was rare, your peers thought you were cool if you had one. I didn't have many and I really wanted some more. These bracelet were the cool things at school everyone had them even the boys. I had so many but I thought I didn't have enough blue ones yet.
Tessa* liked Brad* and she told me about it, I was the only one that knew about it. It was in grade 4 I think or maybe 5 or 3 I can't be sure. She told me to tell know one.
Brad* had a blue bracelet, everyone knew he also liked Tessa*, and he knew that I knew who she liked. I knew this would a good chance to get another blue bracelet. So I told him the Tessa* liked him and he gave me the blue bracelet in return.
I was happy that I'd got another bracelet but I didn't know what the cost would be. I was only young and I had ruined the trust between my good friend. Seen we were only young though we got over things quickly. But I learnt that nothing is worth as much as someones trust for you.
Learn from my mistake to stop it from ever happening from you.
