Hi,

I need your help . Please explain to me, in what situations (contexts) I should use the present continuous and the future continuous to tell about future activities. I'll give you two examples to make my question more clear and precise:

1. I'm working with Mary tomorrow.
2. I'll be working with Mary tomorrow.

1. I'm meeting with my friends from London next week.
2. I'll be meeting with my friends from London next week.

Thank you in advance for your help.
