The missed royal feast

Thamma could narrate stories beautifully. Besides the kids of the household, her audience included the children of the neighborhood too. One fine evening, as she was reading a story about kings and queens, she talked about the names of the sweets the royalties enjoyed. They were 'mandas and methais'.
"Do you still get them?" we enquired. She said she was not sure if they made the stuff anymore.
We kids decided that it was high time that we too tasted the royal sweets. The decision was made by me and my elder brother, the two younger sisters were too gentle to demand such unheard things, but were not unwilling to share the treat with us.
So off we went to our cook, Lakhan er ma, gave her two rupees and asked her to purchase some 'manda' for us from the nearby sweetshop.
As she went for the errand, we waited excitedly at the window, looking at the path in the park in front of the house. It was the route through which the royal delicacy was to arrive.
Soon we saw Lakhan er ma returning, but what is this? She has nothing in her hand. Was the money insufficient? The royal sweet must be costing more.
We were at the gate, demanding an explaination from her.
''Don't you send me to get such absurd things again" she fumed. When she had asked for our 'manda', the man in the sweet shop chided 'manda? Manda na tomer mundu?'.
So that was it.
