Be damned the language barrier, I was writing the exact opposite: we live in a society in which we spend the most part of time either working/driving to work or sleeping. When so much time is devoted to an activity with implied social relations as it's the case of any office, finding someone of interest there can be normal. I'm not advocating that as I have been bitten in the past for that exact reason, I'm just stating that we spend too much time at workplace to ignore relations that could start there.
