My mom would do that too.
"Want to have dinner here tonight? Lol"
"Can you go by and feed the cats? Lol"
"Are you working today? Lol"
Then I found out she was using it to mean Lots of Love.
when all the shorthand txts came out, I too thought LoL was lots of love.
the one that cracked me up was receiving a txt from a guy who said .... ffs - y not?
(ffs = for fuck sakes)
the y made me roll my eyes.
then I deleted him! hahaha ... I mean lol

Maybe it is just so much quicker to write Lol than to spell out his whole name...
