Just now I was having dinner with my cousins and my younger sister, when she asked me "could I try that?" and pointed to my milk shake. Before I even answer, she took my cup and took a sip of it!

I told her "What if I said 'No'? You'd still drink it! Why do you even bother to ask?"

Then she smiled sheepishly and couldn't come up with an answer, like she was embarassed for commiting the biggest crime in the world! (damn right she did! hahaha)

but, since I was such a nice brother that I was I didn't pour the shake on her head and stuffed fries in her face..haha..

The day "could I try that?" becomes a rhethorical question, we'd have polite gropers running around the streets, asking before they touch.
