1. Overhearing my neighbour playing the piano. I texted her to say I was enjoying it; turns out she'll do requests. I could track down some tunes and slip them under her door.
2. Making a cooling cross draught through the flat by strategically wedging some doors open.
3. A small child shouting: 'Can I not like... can I not like...' as if someone was refusing to let it dislike something.
