Need english to german translation?

How do you say this sentence in german;



How have you been since the last time we met?



Please try not to use virtual translators such as babel or google translation. Even with my limited german I will figure it out if you do. This is very important to me as I am trying to reconnect with a childhood friend who left to germany. Thanks for any help!Need english to german translation?
