This is what I wanted to show u, 

I'm nt done with my position in 'hanging up phones' u can do it to others bt nt to me. 

I feel so degraded as a person going against my own principle if I allow you to keep on doing this to me, it's either u stop with this hanging up phone when u get too angry or I'm nt ever gonna speak to u again. No it doesn't give you 'the upper hand' in this relationship, if u want me to respect you pls drop this act. I don't want this "when ever we have an argument u will put the phone down on me, moments to carry on" anymore. 

You know the last time u did this to me prior to that day? If ur mom didn't bake her nice mackerel/curry puffs and that she had asked u to ask me to meet her I honestly wouldn't be talking to you already. 

1. For just nt treating me right (I understand u need to sleep, church day, also hectic post call etc, bt at least call to ask y I cancelled and at least ask what's bothering me in school, I don't think calling could've taken much time) hence I was angry -bt that's in the past. 

(I didn't even ate that day, u ate dimsum, I just felt that u didn't even cared one bit for me, cos u said u didn't even want to know what I ate)  

When we talked d night b4 abt meeting up, the decision was still ambiguous, no confirmation of sorts, and all I receive the next day is a text saying oh I'm going out for dimsum with my parents. (I know u need time with them that's ok, I'll never complain) 

2. For hanging up on me right after

So,

You don't have to loose your cool over the phone, and by hanging up on me u end up hurting me & you'd rather that?  

You could say; I am hanging up now and will talk to you after 'I' or 'you' or 'we' calm down.

I read this somewhere;

To avoid hanging up.

It's called self-control, and you have to not cuss at someone, especially the one you love, nor hang up on them. Stop listening, put the phone away from your ear, but just be calm and wait until they are done, then respond, but do not ever hang up on someone. Just dismiss yourself first as others have said, then agree to talk later. That takes about 5 seconds to do that, and it puts a nice pause on things, instead of huge doubt. Like someone said, once the tooth paste is out of the tube, you can't put it back in

Also it is rude to hang up the phone. 

I am kind and I am worth being treated with love, respect and kindness & can't tolerate ambiguity.
