"We've a lot of catching up to do." and "We've got a lot to talk about." They are the same?

Question

"We've a lot of catching up to do."  and  "We've got a lot to talk about."   They are the same?

Answer

Not always. "We have a lot of catching up to do" means we haven't seen each other in a long time. "We've got a lot to talk about" could also be used in this situation, but it could also be used in many other situations.

Answer

Yes, I would say so.
