eventful babysitting

well last night i was babysittting and it was fine until my mum came to pick me up wit my bro they came in quickly nd locked the door,i asked them wat was wrong and they said that when they pulled up in the driveway a man came up wit a piece of wood in one hand and a semi auto rifle in the other and he looked in the car relised it was the wrong car and walked away, we called the police when they got in but it was still scary the police took the description and said they would ring bk in a mi n my message tone is the same as my ring tone so when the police rang i thought it was a message so i hung up on them cus i didnt look and thought it was a message and i said to myself ill read it in a min i then checked my phone and relised that there was no message and relised it must of been the police and then they rang back so it was ok and then the mum of the boy i was babysitting came bk and we explained wat happened when we left we looking out for him and then all of a sudden we heard a voice say sorry mistaken identy sorry bout before you guys have nothing to worry bout, and i was thinking i feel sorry who it was ment it for then we drove on and we got the numberplate quickly off of the car he was in then as we got up we saw the undercover police car and a normal police car so we went over and updsated them on the sitch i felt very important it was kinda fun part from the thought if he was after us, and that was my eventful night
