When you use your Touhou MP3 Player (yes...I have one; it was getting too small for my regular music so I decided to re-purpose it instead of throwing it out) while cooking supper! And laugh like a madman/woman when a song relevant to Touhou news comes on (like when yesterday, just after I found out about Reisen being in Touhou 15, her Scarlet Weather Rhapsody theme started playing).
