Invited you to play a game! sent by my steam puppet when inviting others

[wvffle]

This seems kind of strange, as when I invite someone to play a game, my own puppet enters the room and sends Invited you to play a game!.

I know it is probably a message that is received from steam but it is still confusing.

Hardcoding You invited friend to play a game! is kind of bad in my opinion, so making the message configurable would be some kind of workaround if you can't get any other message from steam.
