I don't want to spend what my girlfriend is spending on a gift, so I'm going to spend less.
How do you think she's going to feel when she knows the gift is unequal?
She's going to be very upset and she'll never trust me again.
You should be able to get a gift that is close to what's being given to you. It's not nice to go cheap when they got you something nice.
Yeah, but it's kind of funny.
If you want your girlfriend to still be your girlfriend, you'll get her a gift that is equal. Don't you want her to be happy?
