There are many places where you could volunteer (either with people, or with offering some assistance, or with the humane society, or participate in occasional events). You could get involved in arts & crafts activities - either take art classes (your choice - painting, drawing, sculpture, clay, etc), or physical activities (swimming, yoga, golf, fishing, tennis) - and this opens up a lot of other possibilities (galleries, museums, craft shows, markets, etc.). Just a few ideas. If you want to meet many people - start selling Avon or Mary Kay or another type of product. There's no need to feel the void.
