Pro life tip:

If you are ever staying over with friends or family, take an extra iPhone charger/cable put a colour dot or sticker on it and accidentally on purpose leave it behind.

No matter where you are on the social spectrum, these things always seem to be scarce personal items.

It’s surprising, scarce and personal.

The host will always discover it and immediately be glad that you stayed and modify their opinion of you as their “best guest”, which is blurred in their memory with “favourite person”.

Also, it’s nice to give gifts!

I’ve been doing this for a while and it works great, so I’m passing it forward as a nice 21st Century gesture.
