I can't say whether or not it's okey to give presents to ex's.
There's always the MOTIVE. They could be just good friends after love was lost when they were together, one could only muse.
But then again...these days, no one seems to SAY what they MEAN or MEAN what they SAY don't you find?
Honor, they say, is no longer "IN". I say honor is "IN" at any time or any age, it's just a matter of preserving it.
