I tell them ...

Last summer I went to China. I told them, in addition to those mentioned above,

The boy's basketball team I coach (that 14-yr white boy can beat a 16-yr easily, wow!)
The jokes I shared with my colleagues.
The after-life discussion I often have with my colleagues.
Chinese and western proverbs I I often discuss with my colleagues.
How much I donated to the charity last year.
The block party I co-hosted in the summer.
How funny the bus drivers are and how fun it is to ride with those people.
...

In short I told them that there is too much to enjoy, where ever.
