Yes sit in silence a dream!
Imagine, please, that you are good musician attempting to play a lovely piece. Then along comes someone who happens to be tone deaf - and starts joining in with you. Or maybe you are an artist, carefully painting a picture. How are you going to feel if a passing drunk grabs a brush and starts 'contributing' to your masterpiece? Firmly but calmly, you now need to demand your freedom to operate without interference. I'm not casting aspersions on the person in your life who is now cramping your style... just alerting you, in the run up to Valentine's Day, to your need to be strong... and to assert your right to sit in total silence, if you wish, till you have something to say!
