[Morgan Fay]

Just that something's good or bad.

[d.a.n.c.e]

bigger than/less than signs. so okay for example, if i think ryan reynolds is hot/funny/favorite actor/whatever, anything GOOD, i'd say ryan reynolds >>>. the number of those things depends on how strongly you feel. if i hate school i can say something like "waking up early in the morning <<<<<<<"
