Trip To UK

my family decided to go to UK in June, like for a vacation and just take a break. i just got off the phone with my mom, and she was saying that it's expensive and all. i know this trip would cost me a fortune but i really wanna go, i mean for the last 18 years of my life, where have i been to? hong kong? that was when i was like 5 years old, i can barely remember anything now. i do think i deserve this trip for myself, even though it would cost my lots of my savings, but bottom line : it's worth it. i just wanna ship myself off this country and just live another life for 1 month or 2. is that so much to ask for? i mean it's not like i'm making my parents pay for the trip, i would be paying most of it myself but still i do hope they can help me out a little. i wanna see this come true cause it meant a lot to me. and well, i don't wanna be home alone for about 1 month plus rotting at home while my family is on an awesome trip to UK. i hope my parents would understand that.
