She knocked it in when he sat down .He was tired of talking and dropped it in .He dropped it in by accident .It was too close to the river and slipped in .
Why may his phone have fallen into the river ?
To be honest , he had such a strong german , japanese accent when he spoke English I had to focus when he spoke ! ! I found out he lived in Germany for 4 years . I was fascinated with his history and his experiences ! Right , the MOST memorable part of the night was .... we stole our wine glasses and we went out the bar , by the river ... he bent over to sit down ... and his phone dropped into the river ! ! !
