There will be second wave, because first wave showed how partly effective it was. Until people start to follow preventive rules and obey it is no use to run lockdowns. People will still find ways to sneak or cheat the rules. Even wearing masks wont help. The main reasons covid is not cured right now are stupidity of people and stupidly organized work.

How many times times I see 10-15 people walking together, then they put on masks and enter the shop. Why not wear masks all the time?

Our government limited trade of some goods on weekends (you can buy only food on Saturday and Sunday, while other departments are closed). Their idea was to limit the number of visitors in shops. Guess what I saw on Friday evening (pictures from Facebook) - queues to cash desk. People were bulking and not following 2m rule. There was a guy a cant forgot - he was standing in long queue (where he spent minimum 15-20min) just to buy Fanta and potato chips. Can you imagine? That idiot can not survive without them and spend minimum half an hour in the shop...
