From Yahoo! Here are some ways you can develop new friendships:
Get out with your pet. Seek out a popular dog park, make conversation with those who stop to talk on your daily neighborhood jaunts, or make pet play dates.
Work out. Join a class through a local gym, senior center or community fitness facility. Or start a lunchtime walking group at work.
Do lunch. Invite an acquaintance to join you for breakfast, lunch or dinner.
Accept invites. When someone invites you to a party, dinner or social gathering, say yes. Resist the urge to say no just because you may not know everyone there or you may initially feel awkward. You can always leave if you get too uncomfortable.
Volunteer. Hospitals, places of worship, museums, community centers and other organizations often need volunteers. You can form strong connections when you work with people who share a mutual interest.
Join a cause. Get together with a group of people working toward a goal you believe in, such as an election or the cleanup of a natural area.
Join a hobby group. Find a nearby group with similar interests in such things as auto racing, music, gardening, books or crafts.
Go back to school. Take a college or community education course to meet people with similar interests.
Hang out on your porch. Front porches used to be social centers for the neighborhood. If you don't have a front porch, you can still sit out front with a cup of coffee or a good book. Making yourself visible shows that you are friendly and open.
