Being single is actually a blessing in disguise.
It seems to be the trend nowadays.
1. You live for yourself only (freedom)
2. You are not enslaved to commitments (family with kids)
3. You can adapt to alternative lifestyles (choices)
4. You are happy-go-lucky (no worries)
Have you observed this lately?
Your comments.
Let's put it this way, we're born single, and we die single.
That aside, here's the flip side:
1. You live for yourself only, and likewise, nobody lives for you,... ever. Fun? Maybe, maybe not.
2. You are not enslaved to commitments, and will probably never know the joys of a parent's pride, or why your own father/mother smiled quietly as you grow up the man/woman that you are today.
3. You can adapt to alternative lifestyles, until alternative lifestyles come full circle and start feeling like bad sitcom reruns.
4. You are happy-go-lucky, until you realize luck, for some weird reason, seems to favor the young and energetic, but not so much to the old, the frail, and the lonely.
Edit: On hindsight, I think your thread title would be more apt if it is "The joys of being single while young, healthy, and with lots of money!"
