Mail Giant 22.3.14

3 we can't understand...

16a Stored in a box again, need to be moved (6) ?R?A?E
CREASE - RE in CASE, but why the "need to be moved"?

38a Gracious, man, they're only bird cries (5) H?O?S Presumably HOOTS, but why "Gracious, man,"?

24d Concealing a large smile is not so difficult (7) S?M?L?R Presumably SIMPLER, but we cannot se why. Help please!

The words re and case need to be moved around to make crease

[Captain2]

smile = SIMPER
Large = L

[cracker22]

But then there's no definition!

[Captain2]

sim·per (sĭm′pər)
v. sim·pered, sim·per·ing, sim·pers
v.intr.
To smile in a silly, self-conscious, often coy manner.

[bibblebub]

hoots, like gracious, is an exclamation

hoots, mon, there's a moose loose about this hoose

[shaneystar2]

Hoots Mon ....good gracious or blimey :)
( Scots)

For 16? Perhaps the clue should read 'store in a box again' = re-case
