So, you decide to take your parents out for dinner. You know how that goes. "Shall we go out for dinner, someplace nice?" you ask. "Okay, if you like" will be the answer. "I obviously would like," you respond. "That is why I am asking. But would you like to go?" "Okay," they will say, "we can," as if you are doing a PhD in zoology and have asked them to attend a lecture on Grazing Patterns in The Lower West Himalayas and they want to be supportive of your interests.
