Aww thanks everyone. The friend I went with was brilliant. She is very fit and could have done the walk in half the time but she understands that I can't and she adjusted herself to my pace. we spent the whole time laughing And she didn't make me feel guilty at all for slowing her up. No showing impatience or taking the mickey or anything.
Just shows that with good friends we can achieve so much. I think I have learned a lesson from her about patience and understanding and making others feel good regardless of their circumstances.
I was tired when I got back but a good tired. And I must admit I didn't do anything else for the rest of the day, though I felt as though I could.
Thanks so much for all your support too. And well done Shirley.
