Performance!!

Yesterday, I involve a performance is "malan muhibah" this is for the orphanange want. What i think for this performance is really can use my music to bring hope to everyone audience and really inspire them. But, when we played on the stage we cant hear other's sound we can only hear own sound and the person beside us with very low!! but, after our performance end we went down to the end of the hall but, dunno why my heart beat suddenly speed up!! When i settle down i listent clarinet ensemble playing, but i can hear the music very clear when the clarinet ensemble performanced. After finished all the performance we go down to have our meal, i thought we can skiped the meal, so we can go back home faster. But, the person incharge told us "make sure you coming back to take your meal" when we go out to put our insturment. This is the performance that we didnt experience before. although, we also performanced for the charity things but, this time i a total different with that.
