Git Meshige, this actually is working in our favor. If we are expected to be dan l’kaf zechus that they would have said thank you, that means the presumed recipient can be dan l’kaf zechus that we meant to give them the gift in the first place!
Since not writing a thank you note saves money on envelopes and stamps that get thrown away anyhow, just think how much not giving gifts at all will save – no more wasting time and money shopping, wrapping, writing a card, shlepping to the simcha, gas money, tolls, perhaps even airfare and hotel… We can just stay home from the simcha and learn hilchos middos on YWN instead. LOL
P.S. If saying “thank you” has become so passe, then does this mean we don’t have to bentch anymore? Yay!! Moshiach is sure to be just around the corner!!!!!!
