What do you think about me not using the money that my uncle gave me to buy a gift for my mom?
Why don't you want to buy a gift for your mom?
I'm kind of lazy. What she really wants is something I cannot give her.
If he gave it to you so you can do that you should use it for a gift. I'm sure you can find something she will like.
I'm going to buy some type of perfume for her.
It's good that you are doing the right thing by purchasing a gift for your mother. It shows respect to your family when you use the money for the intended purpose.
