Good point snuffaluffagus, I hadn't thought of that - perhaps she did mean lots of love.
The first time I came across lol/LOL in RL was donkeys years ago at work. There was company that did some work for our company, I was the main client contact and the contact at the other company was a guy who was a fair bit younger than me who I got on well with. We occasionally used to have jokey emails, involving the work that was being done. He once ended one of his emails with LOL. I sat there puzzling over it for ages - although we had a good working relationship, I couldn't quite understand why he was sending me lots of love!
I don't think I embarrassed myself or him by questioning it, but I did eventually discover that he didn't love me he was just amused by our email exchange
