Unforgetable experience

Today, I will tell you about my unforgettable experience .I was lost my mobile phone- Samsung Galaxy S6.That is the gift my mom gave me on my birthday.well, I should first that I lost it when I was going back home 2 weeks ago.On the evening that day, after I went off the bus and went on foot about 10 minutes, suddenly i heared the the phone bell was same to mine.when checking,I realized that my phone had disappeared.I got into the panic.To found it, firstly.I went back to the roads I had been to,but not still found it.I felt very worried. Perhaps I lost my phone on the bus.It was already too late and I couldn't run after the bus, so I ran into the first coffee shop I saw.I literally begged someone to let me use their phone so I could calll my number. Imediately, a waiter lent me his phone.My phone rang and somebody answered it. That was the bus driver 's voice.He said that a school girl gave him a strange phone that someone forgot.the bus driver tell me took back my phone on next day...I was feeling relieved right now.Luckyly, I found the phone miraculously because someone must have seen and taken it.In future, I will never be careless like that again...
