Dilemma...

One of my relatives came back from Australia for some funeral thingy which I will not elaborate.. The thing is, she asked my mum to go to Australia for vacation. She is quite close with my mum and she keep on said mum been helping her alot.. Actually, its ok with my bro but he is worry of her going alone.. Since I'm having holiday, he asked me to go with her.. Free vacation, who don't want right? But then vacation with my mum and aunt sounds so boring.. Should I tag along? Anyway, mum's passport expired d, anything have to wait til she renew it.. Lalalalala...
