I've been thinking about having/taking a carefree vacation. I've been thinking about having/taking a carefree vacation.

NoIt doesn't matter where I go, no matter if it's long or short, no matteor whether the destination is nice or not, but as long as it's just carefree. It doesn't matter where I go, if it's long or short, or whether the destination is nice or not, as long as it's just carefree.

But it seems that ithis has not come true. But it seems that this has not come true.

An even smoother phrasing would be: Unfortunately it seems as though this has not come true.

When a vacation comes, I have to be on dutycall, and some office things need me to attend to discuss although I can not make a final decision, or my mom needs me to look after her because the nanny takes a few days off on the holiday. When a vacation comes, I have to be on call, and some office things need me to attend to discuss although I can not make a final decision, or my mom needs me to look after her because the nanny takes a few days off on the holiday.

on call is the standard term I would consider making this sentence into two sentences, it's a tad long.

When a vacation comes,Just when I think I have time, suddenly I have to be on duty, andor some office things need me to attend to discuss though I can not make a final decision,to be discussed or my mom needs me to look after the kids because the nanny takes a few days offis on the holiday. Just when I think I have time, suddenly I have to be on duty, or some office things need to be discussed or my mom needs me to look after the kids because the nanny is on the holiday.

The sentence is a little too long so I shortened it to make it sound more natural.

Sometimes I go out for a few days and wasam all in a hurry and with too much care fullany things ofn my mind. Sometimes I go out for a few days and am all in a hurry and with too many things on my mind.

All though one can be carefree or careless, we wouldn't say that one is care.

SometimesEven when I go out for a few days and was aI'm still in a hurry and with too much care full ofon my mind. Even when I go out for a few days and I'm still in a hurry and with too much on my mind.

So I just want a vacation that I can be careless, free to spend my time as I wish. So I just want a vacation that I can be careless, free to spend my time as I wish.

So I just want a vacation thatwhere I can be careless, free to spend my time as I wish. So I just want a vacation where I can be careless, free to spend my time as I wish.
