I definitely won't take my grandmother to the rock concert

I'll go to Osh by plane because it's faster

I'll probably buy a new bike soon

I think I can't swim because I don't have a swimming pool

I imagine that I'll continue to live in Spain when I'm older

I hope I'll be a famous rockstar and make a lot of money

I hope I won't have a boring job

I'll definitely have a big birthday party
