If you should ever come across a member of the TSFGI in the wild, do not—we repeat, do not—make a hand-heart. No civilian can match the Grand Master's enthusiasm, so this action will instantly expose you as a poseur.
Should you feel the need to do something with your appendages, the only acceptable option is the "look how cute I am" under-chin move, demonstrated here by auxiliary member Sarah Hyland. (The TSFGI haven't been able to lock this one down. Yet.)
