Should I ignore it?

I found out why they were talking about me...
My brother told me that my sister was saying that I was 'grumpy'
and that when she asked me a question I said 'WHAT?'
It makes me laugh... my sister.. can't tell the difference between grumpy and depressed?

I didn't say anything yet... should I?
Like what?

Nah, just go forward with a good, pleasant attitude and keep smiling - she'll wonder what you're up to...Take care !!

Yea I agree wiht amblessed, just go on like nothing ever happened and she'll wonder!
