Why is she being like this?

A girl at work who is leaving asked me to go to her farewell lunch.

We only have 1 hour & it's a 15 minute walk to get there and go back.

I have a heart condition so I get puffed out when I have to walk fast in a short time.

I also have a foot issue where it hurts on the ball of my foot when I walk.

She knows these things and I suggested we can go somewhere closer on another day and she said "Why would I do that?"

Then she said I've seen you walk up and down the city and I replied "yeah, slowly when I can take my time and in my lunch hour."

I would go but it's too far and I can't afford going in a taxi and the lunch is really expensive.

I don't have meetings in my job for myself so I can't use that as an excuse.

She knows I can't walk too fast and I told her yesterday my foot is playing up again.

I don't want to get in a fight but I don't know why she won't understand.
