Verb conjugation of "ripple" in English

Since my wife is pregnant, we must postpone the trip until tomorrow. I am back again in Poland in June and then I would be very happy to meet you. I will email the exact dates a little later.
The conjugations of verbs are the biggest problem for me. I have never studied Spanish in school, but visited evening classes instead. This year I want to take a full Spanish course.
I can already speak a little English but not too well. So I'm more cautious about making mistakes. I want to improve my English, because it is also good for your confidence and communication skills.
