Translation of buttock in German

Hi Christin, how are you? I am on vacation right now, but you can call me if there are any problems. I am planning to meet my students in the end of next week. I will deliver the message anyway.
I only had your other mail so far. Please confirm that this is your email address. Please send me your phone number too. I am happy you are all well... Pictures are amazing and Lola took a huge step forward.
There were heaps of people in this area and we really had to struggle to get through the crowds. We drank a few beers and a couple glasses of wine and being totally tipsy Lili decided she needed to return.
