Yes, I do, depending on the context. I never used to and it caused me a lot of social grief until I figured it out. One thing I learned the hard way is that there are certain expectations that are culturally and socio-economically based. For example, if you have high intelligence/education but poor social skills and you live in an economically-challenged community, displaying your intelligence is asking for trouble. The reason is that the expectation is that if you have high intelligence/education, then you also should be making money on a level with that intelligence and therefore you don't really fit into that community. You should be living with your "peers". The fact that economics forces you to live in an income-challenged community justifies the other residents' belief that education really isn't worth it, all it does is make you "book smart" but "life stupid." Among people who basically have to live by their wits and often cut corners to get by, being "book smart" but "life stupid" is an unforgiveable sin, and they can be merciless whenever you display any kind of ineptness at things that are second nature to them. So, among the people that I live with, I dumb it down.
