It's like people don't remember that even danbooru has tags sometimes. I'll admit, pov_feeding is the closest we currently have to what anon153 wanted, but is it really that hard to come up with a tag like pov_date/dinner/playing_games?

I think that pool qualifies under the untaggable theme criteria of howto:pools, because we currently do not have a way of tagging the viewer's position. We could create the viewer_sitting and viewer_underneath tags if we want to go that route.

As for above ideas:

• pov_date won't work because that is highly speculative. With this tag, we would have to determine the context (party, date, business meeting). And this choice of tags would lump situations other than sitting at a table, such as holding hands and watching movies.
• pov_dinner excludes lunch and desserts.
• pov_playing_table_games would include table_tennis and other standing table games, and would be too wordy for a tag. pov_playing_games is even less specific.

If you have other suggestions, I'll be glad to hear them.
