I actually do the opposite.
Here's something that everyone can benefit from. If the girl is boring
and becomes bored, IT'S YOUR FAULT.
If the girl can't entertain herself and you don't stop her, IT'S YOUR
FAULT.
If the girl asks a ditzy question, I don't believe that it's any time
to "punish her." Instead, I roll past it with frame-control, answer it
very briefly or simply move-on, talking about something WAY MORE
INTERESTING or asking a REALLY SIGNIFICANT question (to get her mind
off of it).
To be perfectly, perfectly honest, though... (and a bit blunt), I
don't spend too much of my time hanging around and talking to girls
apt to ask or talk-about the inane... one dumb question is one thing,
and that happens to the brightest and the best. However, if and when a
pattern becomes evident, I steal control of the conversation, ensure
she's had a good enough time, and excuse myself without causing harm
or damage.
Something to note: her repeating the question, begging you to answer,
may be out of legitimate frustration. Micro-calibrate to gauge; I'm
sure that you, Tracer, are aware of the differences, but for anyone
new to this, coming in looking to learn something, I'd attempt to go
with something less hostile and less risky. I just don't see the
reward (being punched in the arm or having her "beg" for a reply)
being worth the time or the negative potentialities when there are so
many other things that can be done.
With that said, it MAY fit into your personality and "style" of
approach, and that "action" may work for you. I'd have to see it for
myself to determine whether or not something more-powerful could be
put in it's place.
