Find the reason behind difficult
Someone with specialist taste may value a contribution or exact model more than a surprise. Someone reducing clutter may prefer a consumable, service, donation, or shared plan. Ask one discreet question if a wrong guess would be costly.
Look for repeated behavior
Notice what they replace, borrow, repair, carry, or make time for. Repeated behavior is stronger evidence than a broad label such as traveler or foodie, and it helps you choose an appropriate size, format, and level of quality.
Keep the exit easy
Use gift receipts, flexible dates, transferable bookings, or a choice between two options when taste is uncertain. Giving the recipient a graceful way to adjust the gift protects the relationship and does not make the gesture less personal.
