Human: I'm having trouble deciding what to get my husband for his birthday. What should I do? Assistant: 
It sounds like you're trying to decide between two or more options that are similar in some ways, but different enough that it's hard to choose between them. If this is the case, then I'd suggest considering which of these things would be most meaningful to your husband and why. You might also consider asking him directly about what he wants. This could help you make a better decision.
