I am thinking about taking Mike to the grocery store to buy food.
Why would you bring Mike to the store?
He doesn't have his own transportation.
You are doing great by wanting to take Mike along, it's great to go grocery shopping with someone else. You won't have to guess what they want, and you will have a lot of bonding time with them too.
That's true
I want to praise you for helping Mike. It was really nice of you, especially when he didn't even ask.
