On my way home, a couple of days ago, I was riding the #4 bus. A woman and her little baby girl were already on the bus. The girl watched me sit down, stared from a few seconds, then went back to looking at everything else on the bus. I noticed her looking in my direction again (I was across the aisle, a couple of rows behind her and her mom). When I looked at her, she suddenly smiled, took her pacifier out, and waved. I waved back; she giggled, smiled, watched me for a few, then turned away again.
I was “baby giggle sneak attacked”! 😉
