How old is too old (LJ-wise)?

How old does an LJ entry have to be before you decide it's too old to respond to?

Sometimes I don't read LJ for several days and can find myself going back nearly 200 messages on my friends page. That can be 3-4 days and I sometimes hesitate to comment on entries that old, feeling that it's no longer relevant or the person/conversation has moved on.

What do you, my friends, do and what would you have me do if I find an old entry of yours?
