A couple of days is nothing really to a snake. It may be in a pissy mood just because it feels like it and fine again tomorrow or it may just not recognize your scent right away (or it's just being a snake and feels like giving you some grief LOL). I'd just go about your normal routine with it, be calm and don't push handling too much, maybe just a bit of stroking while you do husbandry or something like that. I'm sure it'll be fine. Snakes can't think enough to hate you or be mad you went away for a few weeks. Sounds like it was cared for properly.
