Lets see. Some random thoughts;!.
I bet he knows quite a bit about you like whether or not your single. Suspect he has spoken to someone who does know you well who thus far hasn't said anything to you. He's done his homework.
Question for the girls here?. Suppose that's wrong, girls, and will offend someone here then lets say the female contingent?.
If you were him and you fancied her just how would you go about "engineering" a contact as a lot of this seems these days to be an all roads lead to hell thing?. If he sent you a present or token at your place of work then "how the hell did he know that"! he must be well round the bend!.
If he snail mailed you then how did he get my address?. Was there someone who could have introduced you, how quaint that is these days do people do that anymore?.
Yes i suppose it can be construed as a bit over the top but i bet he thought "I really like her so I'll make a grand gesture so shes well impressed with me that's my best shot"!.
Maybe he's just a bit olde world and a romantic. And the number of the threads here of women lamenting their lack of received affection and romance received and those who do OLD seemly its got that bad that a dickpic is the first thing many expect;!.
Also are we becoming nation who are now so full of FUD ( Fear Uncertainly Doubt) that its affecting us in a bad way?.
And before there's a chorus of what about abusers and other of that ilk yes course that's wrong and perhaps we should be happier that that sort of thing isnt tolerated anymore, it isnt covered up, women's rights are getting better slowly but i think things are improving.
So perhaps the OP ought to at least either take him up on his offer or just send him a note, assuming shes certain where he lives, and simply say thank that's very kind but I do regret etc.
Giving an 8 year old a flower? Well years ago that would have seemed quite sweet, but not nowadays.
Why these days is our first thought that something out of the ordinary is thought of as creepy and or someone's a wierdo, are there that many out there or are they all safely rounded up in the OLD pen after has more then its fair share;!.
Anyway Fish at least your sounding a bit flattered that there is someone out there who is interested in you.
Perhaps a "fortune favours the brave" might be the way to go;?.
Whatever happens do let us all know:)
