How to Humorous Comment on Friends' Travel

Humorous comments on friends' travel reference are as follows:

I envy and hate that you can travel to such a beautiful place, and my mouth is in vain this year.

are you going to use this trip to show off your selfie skills? Remember to take more beautiful pictures and make my mouth water.

remember to help me see what the earth looks like. I can't do without my computer because of too much homework.

I praise you for your trip, and I will be happier if you can bring some local products when you come back.
