Why would she send me a thumbs up reaction a week later on facebook when she sent the last message?

This girl sent me message which did NOT require a reply on my behalf. Then a week later I get random thumbs up reaction on facebook from her. Surely she hasn't accidentally gone into a week old conversation and accidentally send a thumbs up reaction. This was at 6:45am too
