I actually like wasps ... They look cool and they never did anything to me. I only got stung by bees. They are nasty motherfuckers. They sting without any reason, unlike wasps. But you have to be careful with wasps. If they are building nests in houses, bushes etc. they are not attacking humans (unless they feel threatend). If it is the kind that builds their nests in the ground, then stay away, those are aggressive as fuck!
As a child I always saved wasps from drowning in a fountain that was close to a playground I used to go to. I couldn't stand seeing them suffer.
Last year I found the (supertasty) leftovers of a barbeque. Shared the chicken with a wasp. It would sit down on my hand, cutting out pieces of the meat and bring it to the nest, then coming back, cutting more out, etc. It was so amazing and cute to watch.
