Going abroad

Depends on where you're from. If you're an EU citizen, go ahead, it is, legally, like going to another city in your country.
Be careful though, as both the French and Poles tend to have a bad level of English, make sure you know basic sentences as to find your way around (how much does it cost? Where is the train station? Can I please have a coffee/bottle of water/sandwich etc).
If you're not an EU citizen, then you should get a Schengen visa from the first country you intend to visit. If you're looking to do 2 separate trips, you may be asked questions at border control, but if you're doing one trip during which you're first going to, let's say, France and then Poland, make sure to get a visa from the French embassy (or the Polish one if you're going to Poland first).

As someone who lived in France and is often going there, here's some very important advice: don't spend all of your time in Paris, if you can! If you're there for 3 days, then stay there, but if you're there for 5 days or more, it may be worth visiting other cities like Lille, Reims, Strasbourg... They're all beautiful, and have their own identity and culture.

Thanks for the info but there is no trip in sight for short term may go to Italy in spring with my mother

I have a green passport may not require a visa I'm not sure

Well, then you may need a visa, as countries with green passports aren't members of the EU. It may be useful to check whether there's an agreement between Italy and your country!

Yes I will investigate that don't want to return from border today was good Monday back to problems unfortunately

Epic

I wonder in how many days people will get back to their normal lives and be able to travel as they used to before.

I am so fed up with all these lockdown activities... Jesus.
