The thing is... The trouble is... The issue is... Are these all the same, or different?

Greetings! Please could let me know which version of 'you' I should always use when meeting a tutor (first Russian language lesson with them), who is younger than me. It is the formal or informal one, вы or ты please? I don't want to offend anyone.

Пожалуйста, можно вопрос? в чём трудность, в чём сложность? то же самое? в этом контексте: 'Потому что, когда человек говорит, что «ну, бизнесом заняться очень сложно, очень трудно, много проблем». А каких проблем? А в чём трудность, в чём сложность? Ты начал, и у тебя появились проблемы? Или ты даже не начал, ты просто думаешь, что у тебя проблемы?' Спасибо за помощь ))

Greetings from a very soggy UK! Which is right please? People try to avoid taxes. Or people try to evade taxes.

Greetings from a very wet UK! An issue. A problem. Are these the same thing? Do they have the same meaning? What are the equivalent words in your language?

Bonjour à tous! Je ne comprends pas le sens d'un mot ici: 'les houilles'. Pourriez-vous m'aider s'il vous plaît? 'D'abord il y eut la matrice organique où s'élaborer la vie. Dans les marais, les houilles et les tourbières, les bactéries macéraient. ' D'un livre de Sylvain Tesson. Merci beaucoup!

Does everyone think squirrels are cute? Or are they just furry rats with great PR?! They are common here. The dogs love chasing them, the squirrels just scamper away and climb the nearest tree!

How to say to jump on the bandwagon in French? Greetings, I am looking for some English/French language exchange over the next week while I have some free time. And generally on Mondays at 4p.m. for one hour. 50/50 English/French. Please read my profile before replying )) To jump on the bandwagon = To start doing something that others are already doing successfully. Many italki members are asking for language partners. I thought I would do the same.

Greetings! I am looking specifically for someone who can speak weekly on Mondays or Tuesdays at 16:00 UK time for one hour. English/Russian language exchange. 30 mins each way. General conversation only. Let me know if you are interested (after reading my profile). Happy studying!
