Sometimes people don't socialize properly and thats why they end up alone...
Get more involved in public activities... I personally find it easy to make friends in activities such as Aerobic Classes, Dance Classes, Photography sessions etc.
Things that you can find friends who share similar interests with you.
and as many said in this topic, make casual friends, be interesting and always look good...
honestly, you will find the opposite gender knooking your door 😉
I dont expect to find "MY DREAM LOVE" in a club or on Facebook or MSN.
ohh one more thing, do your best to avoid relationships at the office... you dont want to be the center of gossips and many other reasons as well 🙂
just my two cents
