Feeling vandal guilt? Aw… That’s sweet. Why don’t you just get yourself a Grime Writer pen. It’s neat! Just add soapy water and go wild on some filthy street signs, dirt-encrusted windshields and dusty windows. Practice your graff-manship. Put your tag on them. The mucky streets are your canvas! It’s technically clean-up. And best of all, you’re not damaging property or doing anything illegal! Wait, did we just kill your jollies? Bad vandal…tsk-tsk.
