Dear Queenie,
If you give someone a season pass to Carnival or some other series of events, shouldn’t you expect them to use it for all the events? Otherwise it is just wasted money!
Queenie, what do you have to say?—Disappointed donor
Dear Donor,
I say a gift, once given, belongs to the recipient to use, or not use, as he or she sees fit. If there are conditions attached to the gift they should be made clear at the moment of giving so that the recipient has the opportunity to refuse to accept them.
In this case, why not buy the pass for the whole group (your family, I suspect) and arrange among you who will use the pass for which event(s)?
