Well, I just remember the saying....sometimes you're the windshield and sometimes you're the bug.

When he moves 1000 miles away...

When you find out she has no gag reflex

I LOVE YOU

When you feel like it's a good time to say it.
Like after great sex. XD J/k
(Or AM I??? )

Maybe never depends on the relationship. I do not say those words unless I really mean them, I believe there is alot of responsibilities that go along with them. I also personally think alot of people say them way to much and have lost some meaning.

right before you kick the bucket..that way you cant be held liable for anything and its too late for them to start expecting gifts of trinkets and baubles ..i remember the last time it happened and the next thing you know this kid showed up and my money started going to stuff like diapers and formula? wtf is that ..and then as if he knew me he started calling me dada and i said hey ive never seen you before in my life we went to the doctors one day she went into this room for awhile ..
and the next thing you know there it was and there went my money and now it lives with me for seventeen years and it doesnt go away it stays around and now it calls me dad and my money is still going to stuff for this kid that came from the doctors office ..so never say i love you ...the end..

Right after his check clears.

Sounds like true love to me

When I fall in love

Out of the mouth of a babe (8 yr. old I think) I heard:

You really shouldn't say I love you unless you mean it. But if you mean it, you should say it often.

Sounds good to me.

After the first wet dream...

The moment the feeling overcomes you, and don't hold back

I don't have a certain time. I usually say it when I feel it.

I've seen that peom somewhere..and those words ring more true than you know.

Trick question? Uuuuuuuuuuuuh when you do?

When your absolutely certain there's no way you would ever cheat on them. When you only have eye's for that one special person.
