I don't know which sentences I can use to express my feelings. I only hope that I can meet you all somewhere in the future. My friends, thank you for giving me two months of memories. It was a pleasure to know you all.

It means to actually do the work rather than just talk about it. For example, in a business, you might say a manager "rolled up his sleeves" to mean that instead of asking the employees to do it alone, he also helped on a project.
