Help me with my problem.....?

let me just start by saying I love my mother. But I feel she really doesn't try to understand me or my point of view, for starters today we had an argument, we were sitting eating in front of the tv (we don't do it everyday, mind you) and apparently she said something to me and I didn't hear her (well i heard her say something she was next to me) because she was eating so she had food in her mouth and I coundn't see that she was turning to me because i was watching the tv and she didn't say my name. Then she hit me on the shoulder ( not hard she's not an abuser! let just make that clear too) and she got really angry at me and said didn't you hear me, i said no and she said how couldn't you i was talking to you and i sed i'm sorry but she cut me off and said i'm right next to you and can't hear me then she accused me of lying that i couldn't hear her and that i was pretending i couldn't hear her then i started getting a little angry especially for her accusing me of lying... cont.
