What were some of Bruno's reasons for not liking Lieutenant Kotler?

On page 162-163
Bruno, himself, makes a list of reasons why he doesn't like Lt. Kotler. 

 1.
The lieutenant never smiled.  When Bruno asks him for the tyre to
make a swing, the lieutenant makes a joke about another officer having a "spare
tyre"  Bruno notices 

"...his lips forming into
something that resembled a smile" (pg 73)

He also
says that the lieutenant always,

"....looked as if he
was trying to find somebody to cut out of his will."(pg 162)

The page numbers are for my edition of the book, but you should find them in near
proximity to what I have given you.

2.He always addressed Bruno
as "little man".  Again, when Bruno was looking for the tyre, he
addressed him as little man and ruffled his hair.  That made Bruno so angry that it

"....made Bruno want to push him to the ground and jump up and
down on his head." (pg 72)

3. He was
always in the living room with his mother.  Bruno may have been young but even he
noticed that his mother laughed at the lieutenant's jokes more than she laughed at his father's
jokes.

4. Bruno saw him deal with a barking dog by shooting it.

5. His sister acted funny when Lt. Kotler was
around. She was just becoming a teenager and was flirting a great deal with the
lieutenant.

6. Whenever father was gone, the lieutenant hung
around the house and acted as if he were in charge.  The lieutenant was only 19
years old. 

7. The way Lt. Kotler treated
Pavel.  Bruno sees him mistreat Pavel twice.  Once when he asked for the tyre,
and the second time when they were having dinner and Pavel dropped a wine bottle on Lt. Kotler. 
The author tells us,

"What happened then was both
unexpected and extremely unpleasant.  Lieutenant Kotler grew very angry with Pavel and no one -
not Bruno, not Gretel, not Mother, and not even Father - stepped in to stop him doing what he
did next, even though none of them could watch.  Even though it made Bruno cry and Gretel grow
pale." (pg 148-149)

8. The way the
lieutenant talked to Schmuel and how he made Bruno feel when he was confronted with their
friendship.

".....he wanted to say
the right thing to make things better, but then he realized that he couldn't because he was
feeling just as terrified himself!" (pg 172)

"He had never felt so
ashamed in his life; he had never imagined that he could behave so cruelly.  He wondered how a
boy who thought he was a good person really could act in such a cowardly way towards a
friend." (pg 174)

Bruno was  very relieved when Lt.
Kotler was suddenly transferred. He

"....wasn't
around to make Bruno feel angry and upset all the time" (pg 178)
