What I don't like in myself is what I don't like in others

Conversations from this morning....

R woke up wanting to build a surprise for me out of his Lego blocks - for Christmas. He has been building little things because Christmas is his favourite festival. A little later, he came out of his room with a Lego creation of a little Santa on a sleigh with presents, pulled by Rudolph. Then we got talking about presents.
Me: What do you think is the best present/gift you have got?
R: You, appa and myself.
Me: So why do you feel that this is the best gift?
R: I don't know....I love you both a lot....and I love myself....I know it sounds a bit weird to say that 'I love myself'....to hear me saying it about myself...
Me: Why do you feel it is weird? Do you think it is wrong to feel and say that you love yourself?
R: No. I don't feel it is wrong. I just love myself. But it sounds weird.
Me: Is there anything that you don't like about yourself?
R: No. I like everything.
Me: Is there anything that you don't like about other people?
R: Yes. There is one thing I can think of. I don't like people getting angry with me.
Me: Do you like yourself getting angry?
R: No.
Me: Why?
R: I don't know. It is because of the way it makes me feel inside....And with other people, like with my friends, what I don't like about them comes through experience....what happens when I am with them. So if I like them 100 percent in the beginning, then if something happens that I don't like, then it comes down by say 1%.
Me: Ok...so you don't like people getting angry with you....and you don't like yourself getting angry?
R: Yes....What I don't like in myself is what I don't like in others.
