Don`t know how good your French is but try volunteering. There are always clubs & associations looking for volunteers. I joined the Croix Rouge when we moved here & help out on the social side in their "charity" type shop sorting old clothes. They made me fel very welcome & I made loads of lovely friends. There are people of all ages there..in fact I am one of the younger ones - most of the ladies I work with are in their 70s & 80s! I also joined an art class & now love pianting watercolours.
Hope this helps
