One less thing on my list

So after looking back to check the flights last night I saw that from the previous night they have increased by $200 :( I called my mum and told her, and we went through the whole... 'I dont think you have enough money, I dont think youve thought this through, why does it have to be that date?' in response to these comments (I didnt tell her them obviously) she thinks I dont have enough money but when I tell her what I do have shes says 'well that could pay off your student loan' not thinking it through means that she already senses (and has told me) that Im not telling her everything :( this date? what when Ive already changed it so many times for her.. I think this is her pushing it further, I mean come on... I told her I was doing it by the end of the year in April, she was fine with me not being here at xmas. When I told her end of sept I mistakenly said beginning on oct, to which she replied.. well if its october at least stay for stepdads bday (oct 28th) which I am.. so then I decided end of oct right after her bday but there are little in flights.. so now its November 4th!!! yes!! booked!!! woohoo.. and I just emailed the confirmation to bro A too heehee... pray for me girls :) I did tell her I was booking it, so whether she thinks after our 'chat' Im going to change my mind who knows... Allahu alim.. she also made comments about my dad which I cant handle right now.. and told me not to sponge off my grandad, hello?!?! who brought me up?? astagfrillah...
