Khurshid Ahmed asks,
What does it mean when my best friend says I’m a dwarf star to him?
Is your friend an astronomy buff? Dwarf stars are common, small, and not all that bright or hot compared to other stars, so it doesn’t seem like a compliment exactly. On the other hand, at least you’re a star, not just a small irregular shaped moon.
I think you need clarification on this remark. “Tell me more about my stellar qualities, and in particular why dwarf? Is it a reference to my height?”
