I have a few friends, for which I am very grateful. My best friend I have had since I was 12 and I will be 43 next month.
People say I never meet a stranger. Little do they know that when I was younger, I was very shy.
My advice for making friends is to be yourself, be friendly, smile alot. When you are out and about speak to everyone you pass.
Don't wait for people to introduce themselves to you. Make the first move. Give compliments, but not to many - you'll seem fake.
Ask one or two people to join you in something you enjoy doing. I have another friend who she and I really enjoy browsing through consignment shops and antique shops. I didn't meet her until I was in my 30's and she was in her 40's. We have a great time together and there is an 11 year age difference. We met at church. Now we have been friends for about 10 years. We often make a point of inviting other people on our little adventures and by doing this she and I have made even more friends.
I think people nowadays are very busy - often so busy that they don't make time for making and having friends. Don't worry if your house is clean, etc. Get out there and make some friends!!!!
