Gurgling Baby Ringtone

While travelling on the bus today I heard a gurgling baby laugh. Other passengers looked around to see the happy infant, but there was none. The sound was a phone ringtone. Old people's reaction is usually to make eye contact with said infant and then make funny faces to said infant. There was a perplexed look on a few faces, as if their whole world view had just shifted quite a few steps. They looked at each other and then to the owner of the cell phone.
Hearing a sound without having an image to view can be disconcerting for those unused to modern technology. Maybe carrying a fake baby as a prop to go with the phone sound would help? Remember to exercise due care choosing your next ringtone to download, so as not to freak out too many people. Unless of course that is the intention. :)
