Am I a Nice Person?

Am I a nice person?
I wonder this sometimes:
How I project my personality on to others
And what impression I might be making.

There’s a part of me that doubts
That I am nice
And suspects that I’m an irritating presence
At many social gatherings.

I hope I’m not but sometimes feel
That people are forced to tolerate me;
To accept me for who I am.
Do I rub people up the wrong way?

I’m introverted by nature,
Yet can I become too defensive?
Do I get so caught up in my own World
That I don’t realise I’m a nuisance to others?

I'm sure I have presumptions
of how I should be treated:
I suppose I feel that everyone
Should be nice towards me

And yet I think I feel
That I can do whatever I want (within reason)
Perhaps then I'm not nice.
What would others say?

I don’t wish to be self- pitying- yet I
Dwell on past criticisms and generally think
“They were right.  Why could I not see
That I was in the wrong?"

So am I a nice person?
My doubts:  They do remain.
