the forms /tra poco/ e /fra poco/ may be used only fram the time 'NOW' and never
when making a narration of something that happened in the past or for something that will happen after a specified time in ther future.
Examples:
1. ok: sono andato ad A, adesso sono a B e fra poco saro` a C.
2. ok: due giorni fa sono andato ad A, ieri ero a B e dopo sono andato a C
3a ok: domani andro` a B e poco dopo andro` a C
3b. ok: domani andro` a B e fra poco andro` a C
(3a) and (3b) have quite different meanings:
If NOW is Jan. 1 (in the morning), (3a) says that you will reach C on Jan. 3, or Jan. 2,
we don;t now precesiley, but AFTER having been to B.
while (3b) says that you will reach C on Jan. 1 and B on Jan. 2.
