I'm sorry, we'll be fine

I was talking to my mom,
About my grandfather's wake we're going to attend
She started rubbing her eyes,
She looked like she was about to cry

I didn't know what to do -
Half of me wanted to go up to hug her and tell her 'it's alright',
Half of me wanted to run away and not see that sight

Our conversation ended,
I left

I guess I just don't know how to act the way I wasn't brought up
