Baby on Board

I was sat, minding my own business (watching House MD on my PSP) on the train on the way home last night, when a strange thing happened...a couple got on the train at London Bridge, waving goodbye to an elderly pair (grandparents, I assumed), dragging kids behind them...they collapsed into seats and started talking (moaning about their bad timing using the underground at rush hour)...mum was hugging a tiny baby sat on the seat directly in front of me and after no more than five minutes a pair of tiny hands appeared on the top of the seat, searching for purchase, and when found, pulled a little head into view, poking over the top of the seat back, staring straight at me with an odd mixture of awe, puzzlement and terror - I smiled as reassuringly as I could and did a little wave and the head vanished a second or two later as grip failed during a carriage wobble...then the hands reappeared, followed by the head and the same look...I smiled and waved again, and this time baby was repositioned by mum...only for the little head to pop out again, this time around the side of the seat into the aisle...this went on and on for about ten minutes until I heard mum say "What are you looking at?", and she peered around the seat, just in time to catch me sticking my tongue out (anticipating the usual head to appear, causing me a little embarrassment)...it did work quite well as an ice breaker though - we got chatting, I told her Flyingpops and I were expecting and we laughed about the unusual behaviour, but we were both at a loss as to what was quite so interesting about me...I bid them farewell at Redhill (they were heading on to Gatwick) and as I walked up the platform, the little baby *still* had it's eyes fixed on me as the train swept past, and off into the distance...
