When two persons of the same name are there and some telephone numbers are there with little difference and instead of contacting the person you want and contact the other person you wont know what to talk for a minute. I had this experience twice. Once I called my niece instead of calling my friend, both have the same name. Before hearing her voice I was talking something which I wanted to tell my friend and she realised that the call was not for her. I also realised my mistake that time only and felt bad. Today again I dialled my brother in law's number instead of another friend as both have the numbers with a little change in the number. Luckily I heard his voice before I could talk anything and he was surprised to get a call from me. Somehow I managed talking to him and later called my friend.
