What would you do if you got a present you didn't like?

What would you do if you got a present you didn't like? I'm always in this type of situation when it comes  when a person gives me a presents. Well, sometimes. I handle this situation pretty good, because when I open a present I act really happy about it even when I'm not. When they ask me if I like it a respond with a happy smile and say "Yes! Thank You" and I hug that person who gave me the gift. I try to not make a "Fuchi" face. I usually try to use the object or the clothes that they gave me as a present when I see them or when I'm around with them at least once.
