when it happens to me which is rare because i dont really ever hang out with anyone...but when it happens i say to myself that its ok he/she isn't saying anything either so its not just like im not saying anything...and i try to remember that people don't have to be all talking 24/7 there can be silence until one person has something to say..if there is nothing to be said then no one has to say anything...were only human...i try not to be so hard on myself [even though its so hard !!!!!]
