I worked during 5 months for an irish farm in the county Cavan to improve my english, to discover irish culture and to go out of my comfort zone. To put it in a nutshell :

- I fed each morning the horses and the donkeys
- We built solar panels
- I cut the lawn
- I sanded and varnished the boats of the farm
- I cut woods for the forestry company of my host and helped each morning to carry the timbers.
- We restored a tub trap
- I cleaned each Friday the lodge and the boats of my host for the tourists who came for fishing
