White flower in parc

This morning I walked with the father and daughter of the family I visit as volunteer work in the parc. I saw this flower and there was as strong smell. I thought garlic. I don't remember the name. It is a very common flower.

Because today I did volunteer work in the morning about 2,5 hours and the afternoon also 2,5 hours. I feel like having "worked" for 5 hours in total. In my mind it means... I can do it. I feel like coming to a kind of recovery with very small steps.
