Fixing A Charger

I was in Sigma (local supermarket), and I met someone my age that told me to steal breadsticks, i said they werent too good, but he told me that i should steal them so you don't lose anything. Then he proceeded to buy them. The next day, i woke up at 5 AM and my phone was on 18%. So I brought my charger with me while hanging out and I found out there was water in it. Later on i played minecraft with Amber (gf) and there was a toxic player too which just said rude things in chat.
