It’s sort of an unspoken thing, something a friend should pick up on. My female friends have done the same for me when I missed the attentions of my wife when one of us was away. A dab of tenderness or interest is all that’s needed; my older lady friends in particular seem to appreciate this. I don’t do it out of pity—they’re big girls, after all. I do it because they’re worth pleasing.
