If colors could make joy then there must be something about that red and white stripe that breeds happiness, wonder and on the very tense and dramatic occasion...fear. OMG don't fall don't fall don--- oh there's a net there, never mind. Circus = a happy place filled with mystery and excitement. Unless of course you're one of those people who hate clowns... then it's more like hell. :/
