<3 - express it!

In some cases, the marital life is not entirely satisfying, because one's mate is not that interested in the ideas you are interested in, and making love with other people you like in ordinary way - not an option.

So, here is a way how to keep romantic relationships with people who like each other: Instead of exchanging "genes", exchange "memes" - cultural analogues of "genes".

(I use the word 'meme' here in wider sense by including common experiences, because one's ideas are highly influenced by experiences. For example, exchanging movies and books may create common experiences that lead to similar attitudes, ideology, etc.)

In order to explicitly indicate that the reason you share certain things (memetic items) with another person is influenced by your romantic feelings toward that person, and is shared with that intent of "making love in form of exchange of 'memes' rather than 'genes'", use the "<3" symbol in front of your message.

Baked? Maybe, but the "<3" symbol is highly ambiguous. This is an idea of its special use with a very concrete intimate meaning.
