Enjoy the time you spend with them! If you are relaxed and confident they will be also. I love sitting with mine any chance I get. I'm getting older (ugh!) and I sat on a stump that was low to the ground and got stuck and unable to get up without anything to grab! Momentarily I got scared (what if someone gets spooked, etc). My little stallion saddled right up next to me and relaxed his rear leg. I petted and asked if I could use him as a support. I know he doesn't understand all the words, but I really think he got it. Didn't even flinch when I used him to help get up. But then there's my mare who has a new baby. While she lets me do all sorts of stuff with him, once in a while she gets nervous (and it can be from the others getting too close, etc) and reacts. I cannot be sitting in this situation! So, basically it all depends. I think they are just enjoying your presence. I am a terrible leader too and I recognize this. I am a friend before being a leader, which is really not good, but I'm working at it. I'm a pushover until a certain point and send them away. . I also do not sit with the foal because those hooves are very sharp (just learned this little fact the hard way when he stood on my foot!) So basically I'd say--enjoy their presence, if you are comfortable with them nuzzling you allow it, if you even have any thought that could get rougher just let them know it's not ok. I feel so blessed I can usually be silly, affectionate, or just watch them. It's the best therapy to be with them! Knock on wood, I haven't been bitten yet! Pepper merely tolerates my presence (top mare). I can sit with her around IF I am no lower than she is and I can get away in a hurry because she can try her bossiness on me and that's NOT ok. So, be flexible in your interactions. Use your instincts, love them, and don't accept truly invasive behavior. Mine know if I am in a bad mood (even when trying to hid it) and usually stay a bit farther away. I sometimes invite them to me actively, give them a kiss, and then send them off to do their own thing. It's not being mean. They send each other off all time and invite back.
