No means..

..'No'. Not when it comes to my mother though. Sample this:

At the dinner table
Mom: 'Shall I get you a second helping?'
Me: 'No'
Mom: 'Alright.' <Proceeds to add more food to my plate>
Me: 'No Mom, I am full.'
Mom: 'Alright, just finish this. I won't give you anymore.'
<What just happened? I obviously finish off the second helping.>

Me sitting content on the couch
Mom: 'The cushions need to be washed.'
Me: 'No. I had them washed a couple of weeks ago.'
Mom: 'Alright.' <Proceeds to pull out the cushions from under me and around me, ripping off the covers and placing the bare cushions back on the couch. The covers obviously go into the wash.>

Me leaving for work
Mom: 'Shall I pack a snack for the evening?'
Me: 'No. I will be back by 6.'
Mom: 'Alright.'
<On the way to work, the lunch bag feels heavier than usual. I check it to find 2 additional boxes of snacks. Gah!>

I can go on and on here.

Please Mumma, 'No' really means 'No'!
