If the weather isn't absolutely horrid – if it's just sprinkling a little you aren't exempted! – pop out of the house this evening and walk about a bit. Go look at the park or head up to the nearest high ground to get a view into the distance. Or stroll down to the shops and pick up some fresh bread or something nice for dinner or dessert.
Look around as you walk. Make eye contact with people. Smile and greet them as you pass.
