I'm going to pretend that I like the gift my mom gave me.
Did you not like your gift?
It's not something I would have picked out, but I don't want to upset her, so I'll fake it.
Are you sure it's not better to just be honest about the gift?
I didn't like the gift, now stop nagging me.
You can always exchange for something better if the store she got it has a return policy. Just let her know though and make a good excuse.
