Cách sử dụng
The expression "bump up against" means to come across an obstacle or challenge in your path, or to encounter a problem you didn't expect. It can also mean to be in close proximity to something or someone, without being able to move forward. For example, you might say, "I bumped up against a lot of obstacles when trying to finish my project," or "I kept bumping up against my neighbor's fence when I mowed the lawn." This expression is often used to describe unexpected or difficult situations that arise, and is a useful way to convey when things don't go as planned.
