I would like to know if Jack is interested to join us as well. Shared learning is called Tandem. I'm coming in 2 days to Spain. I will pay for the study costs of my daughter, and I assume all other costs as well.
On the second day we drove around Los Angeles. We were totally jet lagged (and so were our kids) and we decided to take it easy on that day. We went to Rodeo Drive as well as Beverly Hills. Both our children slept during the entire afternoon.
In school, we now are learning the grammar part, more specifically, the participles and so on. I understand it at all, but the conjugations, boy they are tough. A lot of patience is needed.
