V.W.
Probably when my 10.5 yr old daughter goes to bed at night. She still wants me to tuck her in and she isn't officially tucked until she has taken her arms out from under the covers and has given me a full hug/squeeze (at her insistence that her arms be out - the only way it counts), then when I tell her I love her she says "I love you more!" Once in a while, she'll throw in a "Mommy", which she doesn't call me anymore.
My son, 13 yrs old, also still expects a full hug every day. At bedtime, and usually several times throughout the day--especially when he sees I've been stressed (usually due to something related to him, lol). And he doesn't like to let go.
