When I got to Celle, I wandered around for a while trying to find the bus station by following the signs which led me to another platform in the train station, and then I had to go down some steps to get to the bus loop. I checked out the bus schedule, which was in German of course, and waited for my bus to come in roughly 10 minutes. Waiting, waiting, waiting...... for about half an hour and no buses came at all. Actually, no vehicles came at all, so I decided to go back to the train station to ask if buses ran on public holidays, but all the shops were closed except for one, and the lady didn't speak English at all (we tried talking earlier when I bought a postcard from her, but we both didn't understand each other so we just smiled at each other and both shrugged our shoulders). So back to Hannover I went. 

In the afternoon, Kitty and I walked to Herrenhäuser Garten (only two tram stops away from our place), and explored the park surrounding it. We thought that this would somehow lead into the Großergarten but we were wrong and walked almost all the way to the freeway. It turns out that there's a moat separating the park from the actual gardens but you could still see inside. Next we went into the Berggarten, checked out this free outdoor photo exhibit (pretty nice but a little crowded) and walked around under the trees and checked out the mausoleum where the ancestors of the British Royalty were buried, the former rulers of Hannover. We both decided to go back home and rest and plan our Hamburg trip, but really, for me, what that meant was, "I think I'll go to sleep for the rest of the day because we have to go back to work tomorrow".
