Step Brother Plan

I closed my flat door and walked off to meet my Mum for lunch, that's what I thought. I arrived at the restaurant and walked in. Standing behind the bar was Andrew Wilson, the restaurant owner. I walked towards the bar and greeted Andrew with a handshake "Afternoon, Andrew, is my Mum here? " I asked him, Andrew smiled, Your family are sitting over at that table. 'Family! What are you talking about? Andrew, my dad passed away three years ago" It dawned on me, I looked over at the table "My Mum got remarried.
As I walked over to their table, my Mum saw the look on my face [Oh dear!!] Mum thought. Mum got up from her chair to greet me, and we hugged "Mum! Do you have something to tell me?" I asked her, "Yes, dear! I remarried and forgot to tell you," I said, smiling. "No! Mum," I replied, "Tom, this is your Dad, Simon Peterson, and your Brother, Tim Peterson" Mum introduced them to me.
I pulled out my chair from under the table and sat down. "Hello, sir. Nice to meet you and you, Tim," I said with a smile. "It's nice to meet you, young man," Simon replied. "Nice to meet my young brother, " Tim said with a smile. "Tim, I am not your young brother," I replied. "I may look young for my age, but not what you just said." I replied, " You look and are built like a 14-year-old boy, especially in those shorts." Tim answered.
