General ⇒ Vertical centering within the Parallel environment

[Heresy]

Hello everyone,

Using the Parallel environment, I would like to vertically center a sentence (Left 2) in the left column to match two sentences (Right 2a and Right 2b) in the right column. The LaTeX file and corresponding PDF output are attached. Here is the current MWE:

Code: Select all

\documentclass[a4paper,11pt,twoside]{article}

\usepackage[top=1cm,bottom=1cm,left=1.3cm,right=1.3cm]{geometry}
\usepackage[T1]{fontenc}
\usepackage{inputenc}
\usepackage{parskip}
\usepackage{parallel}
\usepackage{lipsum}

\begin{document}

\thispagestyle{empty}
\pagestyle{empty}

\vspace*{5cm}

\begin{Parallel}{2in}{6.0in}
	\ParallelLText{
		Left 1 \\
		Left 2
	}
	\ParallelRText{
		Right 1: Lorem ipsum dolor sit amet, consectetuer adipiscing elit. \\
		$\bullet$ Right 2a: Aenean commodo ligula eget dolor. Aenean massa. \\
		$\bullet$ Right 2b: Nullam dictum felis eu pede mollis pretium. Integer tincidunt.
	}
\end{Parallel}

\end{document}

I've tried so far \vspace*{1mm}, the minipage environment, the parbox environment and \pbox[b]{\textwidth}{Left 2}. None of them seem to be working.

Thank you in advance for your help.
