No, it absolutely
is weird, but also unethical. Sure, people do it, but it is still weird and unethical, and I don't care how socially aware you believe you are or how comfortable you are doing it. Also, common? Sure, but not in the sense you mean. You mean it is prevalent. Of course I have not worked everywhere, but I disagree. I'd say it is less than a tenth of a percent of individuals like yourself that would engage in romance
while working. Such a small percentage doesn't make it prevalent, instead that makes it an exception.
I suppose if your office romance doesn't work out, you're perfectly comfortable with that outcome and move on to other coworkers like the office is your personal brunch buffet. You can meet people pretty much anywhere, but the one place that it is tasteless to romantically socialize is the place you are being paid to work. You see, normal mentally healthy people don't need to find romance at work, though they're socially aware enough to do so, they simply don't need to because they probably don't have such minuscule prospects. Mentally healthy individuals will not, by and large, need to take advantage of having such a captive audience as a colleague or coworker or staff that is stuck at work, working. What is far more prevalent, thank goodness, is that most don't treat their boss's office like a singles bar. In all honesty, your post is the creepiest thing I've read all week. What if what you interpret as social awareness is instead a deficit of self-awareness or oblivion? Because if you behave this way, you are completely unaware of or simply do not care how others feel. It's probably the former, which you probably hide with the latter. You don't know, so you you'll tend to say you don't care.
Other behavior that is not OK? Even when you're not working, it's really not ok to try to romance someone who is working. People do it, but it sucks. Even a little harmless flirting with a cashier you think is cute is less than ideal behavior. I refer again to the captive audience part. Try romancing someone who can get away from you, if they wish, without jeopardizing their job.
Like at a bar. Can you find romance in a bar or singles mixer instead? Because I guarantee you any innocent bystanders to your romantic prowess would prefer it occured anywhere but where they work. But you would know that if you're socially aware.
