Missing

Wanted: M
Last seen: Weeks ago
A few recent M sightings:
In the alphabet spaghettios in the cupboard
The famous golden arches we drive past every day
As heard in the alphabet song we sing in the car
I hear myself and others say it all of the time, so I know that M is in fact still a valid letter, it doesn't seem to have been eliminated from the alphabet. But there is one little boy who has for the most part stopped say "M". I'm not sure why, but I miss it! Yes, all those other sounds and chatter are great as well, but there is just nothing quite like "mamamama".
