surprise for friend need ideas

NittyGritty

ok this might be a bit silly but here goes..

my best friend (female) as had a bad time of it lately, bit down through one thing or another etc etc, I love her to bits (not in that way) ....ok maybe I do deep down but she don't know that as I have never told her that.and don't plan too either as I know she is way out of my league.

anyway moving on theres one special place she loves to take her dog for a walk, and sits near a small stream,while the dog roams free she lets dog paddle in it etc, its quite picturesque peaceful place

I was kinda of thinking of doing some kind of surprise around the area she goes most days with her dog,its kind of a woody area but ,near the edge of pool/stream ... I was thinking drawing something in the sand or the soft part of ground near the edge of stream where she always goes and sits, something like your my bestest friend things will get better, or something kind of uplifting kind of wording, with some flowers in a heart shape maybe? and I don't know maybe a picnic basket at side bottle wine, just to cheer her up (just purely as friends)

its just purely to cheer her up and to let her know she as friends around her etc. just think it be a nice surprise when she goes take dog for a walk and sits in her fav spot (abviously I will go down and do it all up before she goes with dog so she will be totally surprised)

so any ideas ?of what to write in wording that will sound ok without going overboard, and maybe some flowers in a heart shape kind of thing?

I will add a pic of location give u better idea of what I,m talking about
