question about reported directory size

[Robert Huff]

huff@>> dir /usr/lost+found/
total 192
drwxrwxrwt   2 root  wheel  194048 Feb 23 13:01 .
drwxr-xr-x  22 root  wheel     512 Feb 23 03:38 ..

	Now I understand the 't' in the permissions ... sort of.
	a) does this mean the reported directory size will never
		shrink?
	b) is that the actual blocks in use, or an artifact?
	c) is is safe to delete and recreate the directory?
