Here is a story, that just happened to me!
Today, i had come back from the shop and walking up my garden my path, i noticed a garden spider, near to my front door that was buisily spinning her web, i watched her, and when she had finished i stroked her and said how beautiful she was.
then, when my son came back from work, he went upstairs, and being the only one would came in through my door since i came in.
about half an hour after, i saw a garden spider crawling up my leg, i picked her up and thought how she got in my home, well it looked like the same spider…so i went outside and noticed her whole web had vanished.
it was the same spider…
so i put her back on the leaf where she started her web
i think she trusted me and thats why she she crawled up my leg.
conclusion: spiders can communicate with those who show them love
