May Your Projects Succeed

All year you've said I may redo my garden and I may clean my roof and I may put in a new light switch so I can see if the opossum family in the basement is getting larger. And guess what? It's May! So buy a bunch of this stuff and get started on all those projects. Especially lighting the opossum family. Little Perry Feral barely even knows who you are.
