I just don't understand it. Why are there some people claiming to look for help with Spanish and sending lots of messages, just to say afterwards that they are too busy to study Spanish. If I were one of them I would simply not message anyone offering a language exchange or help. I received this week seven messages offering help from people who don't even care about replying back as a sign of politeness, when they were the ones who first messaged. Would not it be easier to not offer help when learning a foreign language is very low on your priorities list?
