My head hurts, so I can't work now.

She is healthy now too, so she goes by the stairs and not by the elevator.

My stomach hurts, so I want to rest at home.

My throat hurts, so I am drinking water.

I don’t have a ticket, so I can’t travel by bus.

Sometimes I do not decide quickly, so I ask for another minute.

She found a better price on the internet, so she is not exchanging the shirt.

There is a lot of noise in the office, so I cannot listen to the conversation.

The drawer is under the shelf, so I always find it quickly.

There is not much battery left in my phone, so I am charging it now.

This conversation is important, so I want to speak quietly.
