They may be brothers but Lyle definitely got the "lion" share of brains as
compared to Frank.  While Lyle gets how things work Frank seems to
struggle.  Along those lines Frank will whine for food from an hour before
dinner until an hour AFTER dinner.  Lyle will meow once and when I tell him
it is not time yet he moves on and waits patiently.  I have even noticed
that when Frank is on a particular roll Lyle will find the furthest spot in
the apartment to be.  I think Frank even bugs him with his meowing.  It
seems that when Frank whines Lyle will come over and meow also (one meow)
thinking it must be dinner time.

So the other day I am in the kitchen and using the microwave which Frank
thinks is a cat food maker and there is Frank on the table crying for food.  
In comes Lyle "meoow" "no boys, it's not time yet" Frank continues to whine
so I say "oh be quiet, you are making everyone crazy" when Lyle jumps on
the table and smacks Frank on the head a few times.  I was pretty surprised
since he does not do that.  I think he was mad that Franks makes him run
over for food all the time and it is a false alarm.

I can hope Frank takes the hint from his brother but, sadly, it did not
look like he understood the point.
