Right alignment of two left ragged lines

Question

I have two small lines of text with different width. I want flush them right keeping their left justification and the line height of previous text.

\documentclass{article}
\usepackage{fontspec} 

\usepackage{lipsum}

\begin{document}

I was yet young in life, which I had begun early; but my intimacy with him was of a recent date: we had been educated at the same schools and university; but his progress through these had preceded mine, and he had been deeply initiated into what is called the world while I was in noviciate noviciate noviciate.

\hfill\vbox{\hbox{Foo}
\hbox{Foobar}}

\end{document}

Answer 1

You can use a tabular with [t]op alignment.

\documentclass{article}
\usepackage{fontspec}

\usepackage{lipsum}

\begin{document}

I was yet young in life, which I had begun early; but my intimacy with him was of a recent date: we had been educated at the same schools and university; but his progress through these had preceded mine, and he had been deeply initiated into what is called the world while I was in noviciate noviciate noviciate.

\hspace*{\fill}
\begin{tabular}[t]{l@{}}
Foo\\
Foobar
\end{tabular}

\end{document}

Answer 2

The simplest solution is to put a \strut both at the end of the preceding text and inside the \hbox:

\documentclass{article}
\usepackage[T1]{fontenc} 

\usepackage{lipsum}

\begin{document}

I was yet young in life, which I had begun early; but my intimacy with him
was of a recent date: we had been educated at the same schools and
university; but his progress through these had preceded mine, and he had
been deeply initiated into what is called the world while I was in
noviciate noviciate noviciate.\strut

\hfill\vbox{\hbox{\strut Foo}
\hbox{Foobar}}

\end{document}

But using primitive boxing commands in LaTeX is not recommended.
