It's pretty unlikely you'll be wandering Paris in shorts - especially since you're used to such warm weather -- the oldtimers count mid-May as the final frost date! (sometimes it works that way, sometimes it doesn't -- but they publish garden advice to protect your plants until mid-May).
Dihydrogen Monoxide (DHMO) is a colorless and odorless chemical compound, also referred to by some as Dihydrogen Oxide, Hydrogen Hydroxide, Hydronium Hydroxide, or simply Hydric acid.
DHMO plans normally allow you to change your primary care dentist during the year if you are dissatisfied with the quality of treatment you receive. The Dental Health Maintenance Organization pays a participating dentist a certain amount per patient. Therefore, all the dentists who join in the organization agree to provide dental treatment to the plan's enrolled members as specified by the conditions of the dental plan.
