Answer: Dear Sister,
I know you have made a long way from our home to port harcourt, now you have grown big in your life. You can take your own decisions. You have a lot of freedom when you are at your own house, but over there you don't have an option but you have to stay with your uncle. Uncle are a very close relative to our family but then still, at the end its not your own house.
I want you to understand that you are really far away from our home, so we can't tell you do this do that, but its our responsibility to make you understand that you need to behave well in the city. Plus you are living with your uncle so you also need to give respect to his people in the house as well. Don't do anything that will cause trouble to your uncle. You also need to understand that it is a whole different country, different country means different rules different currency and different everything. Please be cautious of what thing you will do while you are there and take care of yourself. We all over here LOVE you!
Explanation:
Lets begin with the definition of an idiom:
An idiom is a widely used saying or expression that contains a figurative meaning that is different from the phrase's literal meaning. For example, if you say you're feeling “under the weather,” you don't literally mean that you're standing underneath the rain.
To me "under the weather" means not feeling well, my assumption being that the rain is the symbolism for sadness.
