I must say, having attended meetings of various other denominations, I can say that none are graced regularly by the pure spirit witnessed at Mormon meetings. This gift, borne by the Restoration, cannot achieve it's full splendor under quiet conditions. Therefore, don't be afraid to talk, laugh, cough etc during a meeting. Prayer may help too as will spiritually veracious testimony, but if the spirit still refuses to dance don't worry, it's God's will! Rest assured there are lots of good reasons for it to disappear from view now and then. In any case, only a very greedy child expects to receive treats all the time. :)
