My calendar has never been so full. I was not one of those people that needed to check their calendar for much. When I was in school I was busy like crazy but nothing I couldn't memorize. But now, with the wedding, meet-ups, making appointments to hang out with friends (we are so much older and busier!); I have to consult my calendar. Makes me daydream about having a blackberry. I can't always check my personal email anytime I want and even then, my iCal is safe and sound on my laptop at home. iCal is the best, the only con I can report is that the link doesn't show up on my attendees' invites.
But I'm sure that after the wedding, my calendar will clear and things will be as they were. Or am I completely delusional?
