Riddle me this:

My first is in sawfly but not in flyway

My second is in sensitivity but not in seventy

My third is in extort but not in retort

My fourth is in achy but not in cay

My fifth is in resuscitation but not in nonresistance

My sixth is in crossness but not in soccer

My seventh is in disconcert but not in intercessor

My eighth is in intoner but not in intention

My ninth is in cassette but not in cast

My tenth is in medicine but not in imminence

and if you can’t solve the riddle, may be a poem will help:

Many happy returns Daily Create ride into the mouth of freedom, the thousand creates…and beyond!
