Gents: Be careful how intently you focus on your work on your first day at a new job. You might not notice a female coworker coming up to introduce herself. No matter how breathtakingly attractive she is, do not allow yourself to be jarred enough from losing your laser-like focus to blurt out "Holy God, you're beautiful!" She will be a married mother of one, you will both be horribly embarrassed, and she will not make eye contact with you for a month.
