How do I continue a function that has wait()

local function Test1()
    print("function started")
    wait(1)
    print("function ended")
end

local function Test2()
	print("About to call function Test")
	Test1()
	print("All Done!")
end

Test2()

if I run this (untested) local-script , the script will first run function Test2() and then it will automatically run Test1() because it's in the Test2() function. The thing is , the print("All Done!") will not be in the output before 1 second later because Test1 has wait(1) in it.

Question : How can I print("All Done!") without waiting even though Test1() have wait(1) ?
