Where to start …

Weird thing happened yesterday, fired up the Volare drove to the store (side streets, appx 1 mile), parked killed car went in for my daily coke and snack. Came out started car, and now the brake warning light wont go out. Never touched parking brake but checked switch, was still connected, even tugged on it against the spring and light never flickered. The brakes are as they always were and feel normal. I even gave them a good hard few pumps to see if the pressures were amiss and they really didnt pump up but never triggered the light off either. So question is, where should i check next?
