 Cool, hi, welcome back with, well not welcome back, we're already talking, we're sitting here rambling on differential reinforcement of alternative rates. You could sleep around town or you can get married. Both include the same amount of sex, one's just more appropriate. D.R.A. Did you see other videos on condoms? Yes, yes, see other videos on condoms. Not that we're sex maniacs, but, anyway, woohoo, yeah, woohoo. Maybe the F.T. is just a little long, no. If you know what I mean. Yeah. Anyway, another one would be that I've seen and implemented a bunch of times, a D.R.A. for asking for break. Instead of having a kid clear the entire table of everything and bite scratch and scream and potentially throw his chair, you can prompt him to verbally state he needs a break. It's much more effective.
