I think asking her ahead of time, what method of greeting would be okay with her is a good idea. I don't care for hugs, but will force myself to go through with it with certain people--some close relatives, also pecks on the cheeks with them. It upsets them too much if I don't, so it is less hassle to go through with it. For some reason, I don't see hand shakes the same way. It is much less personal to me, and is something done typically with someone one has just met, so it doesn't bother me, although I do have trouble sometimes in figuring out if something is a "hand shake" situation or not. However, some aspies may not care to shake hands.
I am all right engaging in physical contact with animals, though, unless it involves something like biting or clawing. I have rarely been bitten by either dogs or cats, but cats often like to claw even when playing, which is a problem for me, as I don't like being shredded. I do like cats, though, in spite of this,
but I am more of a dog person.
