Good morning TD, I don't think it was a coincidence. I think it was your friend, and that he may have been trying to contact you or let you know he was around and to pass on these messages to his mum. Every boy's (and man for that matter) mum is their universe and he must have had so much love for her that he needed these messages to get through somehow, and you are the most receptive.

I don't know Lisa Williams, or what she said was really about. I do know that it would be hard to go and talk to your friend's mum again though.

I think, as hard as it may be, that he delivered his messages, he knows they got through, and now he could move on. I am sorry you miss your friend.
