Step 1: What you'll need
Plus, you don't need much to sit on your stoop: just your stoop, and a butt ... preferably your own ...
Step 2: To avoid stoop-butt, you can sit on a chair
Step 3: Invite friends ...
Fuzzy pets also make nice stoop buddies. I notice when I sit on my stoop with my cat, people are more likely to say hi.
Step 4: Or have some "me-time" on your stoop
(Less picture-friendly activities including clipping/painting your nails, brushing aforementioned fuzzy pet, or writing your personal manifesto.)
