You shouldn't need an excuse to send your sister an ecard, but in case you do, today is National Sister's Day. Channel your sister's ability to make you laugh or cry by sending her a funny Someecard. Share them with her and LOL over your special relationship, because at the end of the day, she's the only one you can send these to who will really get it. Now that's love.
