Today's swimming class Today was my fifth day of swimming classes. I'm taking this classes because I want to learn how to swim. This is very important for any person and I think, speacially for teachers because more than once you will go out with your students and if there's an emergency you will be able to rescue a student who can get in trouble with water in the swimming pool I'll become a teacher, by the way. I'm glad that today I could float on the water so that might be a good sign that I'm learning I hope to learn as soon as possible to start swimming as a shark, fast and confident underneath the water.

When to use the word though? I've seen this word many times but I haven't figured it out yet. Can someone explain it to me? I'd rather you give me the meaning and also some sentences to get it... Thanks in advance for your answers.
